@WorldLeaderPretend you’re 100%. Nothing affects someone’s mental health more than being told (or feeling judged) they’ve done ‘bad’ things on purpose because they’re a bad person or set out to be disrespectful or cause harm. It’s especially damaging if a parent feels this about a child. So, support for the DC’s should be a priority.
Shit happens, people are careless, lazy, forgetful, deceptive, rude, aggressive. But that doesn’t make them a bad person. It makes them someone who (with support if necessary) needs to hold themselves to account for their actions, apologise for the impact on others, take responsibility for the consequences, learn from the experience. And grow. TBF to OP, on the face of it, she’s started to do that. She’s having a breakthrough rather than a breakdown.
It’s tempting in these situations to get mired in fault and blame. Whose fault is it (OP, DH, DD)? What’s to blame (past trauma, toxic household etc)? But that doesn’t really matter.
What matters is going forward, not looking back. Via accountability, apology, responsibility, learning and growth. Everything is solvable and fixable. IMH (and untrained) opinion, that’s what OP needs to focus on. And that’s what her DH and DD need to focus on too. If they can all give themselves grace, respond with love, empathy and respect for each other and a desire to face life as a strong family unit (even if OP and DH don’t live together if there’s a risk of DA), it’s really not too late.
They just need a reset. It sounds like they’ve been juggling a lot since the first DD was born traumatically, with no family support on OP’s side. It wasn’t the easiest start or set-up. Self-employed people can’t usually take time off without losing income. It’s extremely challenging for someone with ongoing health problems to be a full-time home carer. The kids are now older and will become more and more independent. This means the hardest (childcare) years are over.
So (when she’s feeling better) OP now has the chance of her own life outside her home and caring for her kids. It doesn’t have to be paid work. She could volunteer or study part-time. This may help her find herself again, rather than being solely ‘mum’, whose main job is to ‘manage’ her kids and home. She can make her own friends, build her own life and get her confidence back. She’ll have more time to get treatment, get healthy and consider how to become financially independent.
When kids become teenagers, you need a reset in parenting. They should be treated, and behave as, young adults. Not ‘told’ what to do and ‘told off’ if they don’t do it, but expected to take accountability for their actions or face consequences. DCs gets basic pocket money in return for certain household chores while they get support and focus on school. But if DD1 wants more to spend, she has to get a part-time job. Teenagers can bring new parenting challenges, which OP and DH need to rise to as united co-parents, with equal responsibility, modelling healthy adult behaviour for their kids. Teenagers need a lot of love and humour. They need to see people being loving, respectful and calm to each other. They need regular on-on-one time, ideally with each parent.
Tomorrow is a new day and a new chapter. The first day of the rest of their lives.
