Absolutely this^^. Great post!
Your family hasn’t fallen apart op and I don’t think it’s helpful to frame it that way.
What I see when I read your op is that you are a conscientious parent who is despairing and weary of her youngest teen’s behaviour and that you are struggling to implement boundaries with her. And that you are worried about your eldest and the relationship between the two sisters. And that this situation is dragging you down emotionally,
I hope this doesn’t sound patronising op bc it’s not meant like that at all, but I think you need to believe in yourself a bit more. Be a bit more confident when establishing boundaries. This isn’t a catastrophe this is normal life with stroppy teen girls who are only half-baked. I went through hell with one of mine and she didn’t even go off the rails in a conventional sense; she was bright and feisty and was mean to us all at home because, like a toddler, her competence and ability to look after herself in the outside world did not match, at that time, her ambitions for independence and freedom. And boy did she make us all suffer for it! She was also, as it turned out, depressed, and this manifested itself as anger.
Behaviour is communication op and you need to try and find out why your youngest is behaving this way. It could just be normal teen angst. Is she jealous of the relationship that you and your elder dd have? It might partly be personality but she might be massively insecure and crying out for boundaries from you. Your “frailty” as she sees it is giving her the subliminal message that problems can’t be handled! Or she is bored and depressed and picking on you both to get dopamine hits?
Whatever it is, and the way to find out is to spend time alone with her, don’t allow yourself to be dragged down with it as it is a phase which will get better. It might be a five year marathon, so you need to bolster yourself up for the long haul, knowing you will all come out of it ok on the other side.
Step one : SELF CARE
Your teens are watching you op and your youngest one is testing you. They are waiting to see how you handle all of life’s challenges.
You are their rock or solid foundation from which they spring off in to the world. They need to check that it’s solid before they leap!
They are also looking at what you do, not what you say, Be the best role model and example you can be! Give them a reason to mature; show them that adulthood can be fun and fulfilling, not just a whole weight of problems on your shoulders.
And in order to do this, you need support! Parenting teens can be so lonely and draining on your own. Try and find a licensed psychologist; an older woman, someone who has experience of adolescent development. Even if you can only afford to see her once a month. Sell clothes if you have to. You need someone to bounce ideas off, as all of this is a heavy weight without someone to consult with.
See your gp and talk about whether you are depressed yourself, or need some extra vitamins or supplements. Attend to your sleep, your diet and make time to exercise.
And lock up your valuables and start doing things outside of the house! Get a hobby! Do something creative! Something you enjoy! By allowing the fourteen year old to dictate what happens in your home; you are giving her enormous power to run things the way she likes! Go out if you want to go out and make sure she is in a class or activity when you do, Or with another responsible adult whom you pay to look after her. If she can’t be trusted to behave at home while you are out, then this is the consequence!
You can’t look after others properly op until you look after yourself properly! And teens can drain you and it’s easy to get sucked too far down the rabbit hole of worry with them instead of sitting a reasonable distance from the entrance and waiting to see where they pop up!
Step two: BE STRATEGIC
Take an emotional step back and choose your battles. Don’t micro-manage. Don’t get involved in squabbles. Step away when your youngest is mean to you. She doesn’t get to communicate that way with you full stop. Change the WiFi password if you have to. Leave the house if you have to. And step in emphatically when she is mean to her sister. Emphasise the sort of home you are trying to create but don’t try and manage their relationship either.
Make sure your youngest has lots of distractions. She has lots of energy at the moment to bait people and that needs channelling in to something more productive. Get her involved in something which is challenging for her and out of her comfort zone (that usually inculcates a bit of humility) and mastering something challenging can boost self confidence. What about the Duke of Edinburgh award? Volunteering at a pet shelter? Helping out at a riding stable? Learning to be a lifeguard?
Step three: improving individual relationships
Get to know both of your girls by spending one on one time with them for now. But insist on some family meals during the week and cook them all together. Once a week if it is hard at the beginning. Get to know each of them and their individual worries. Your eldest may be spending time hiding at school bc her younger sister is humiliating her in front of her friends? Find out about that. She is probably a little cold towards you because she feels that the younger sister’s issues are being allowed to dominate the household and she can’t trust you yet to handle it, So communicate with her. Take her out to dinner. Take her on a drive. Get a baby-sitter for the younger one if you have to. And a safe to put your valuables in while you are out! Or make sure the youngest attends an evening dance class or martial arts class once a week and take the eldest out them.
And then do the same with the younger one. Talk to her. Don’t let every interaction with her spiral down in to negativity. Have fun times too with both of them.Run errands together and build in a bit of a fun stop on each outing. Some junk food or a trip to a clothes shop.
It’s helpful to switch your parenting strategy now from “top down” to “running alongside”. It’s tempting to get stuck as parents and not adapt to your teens increasing abilities. Can you give your younger teen more responsibilities and power within the home for example? Could she plan some meals? Shop for them at the supermarket? Give her more choices if she feels stifled? Try to get your home to run more as a collective where “young adults” are living together and negotiating abd sharing a space rather than you managing every detail. At the same time, you need to ensure that agreed rules are followed through.
This all takes a lot of energy on your part when presumably you are working too but you CAN do this op! You have to believe in yourself. You are not failing. You are parenting on your own and that’s hard. Just know that it will all come right in the end. Invest in yourself and invest in the relationships with your girls and it will come right I promise. This too shall pass!
My eldest was incredibly difficult for five years and she raged and raged and it drained me completely, and the more I was drained, the angrier she got, it was a vicious circle. Now she is in her early twenties she is back to her delightful, humorous, curious, considerate, dynamic self! I can hardly believe it but it’s true!
Could you catch a break this summer btw and send the youngest to spend a week to ten days with her dad? If he is trustworthy? That could be your time to take a wee holiday before implementing a new strategy when she returns. Is she mature enough to start travelling unaccompanied with a parent meeting her at either end?
Good luck 💐
