Struggling with my 18-year-old daughter’s sudden change in behaviour

My dd18 (just turned) was such an innocent girl. Has horses and just enjoyed life.

the last month or so she has done a complete 180. Met a lad, been going out until 1/2/3am multple times a week, drinking more, barely going to see her horses, talking about getting another tattoo that she hasn’t put any thought into because it was a flash sale lol, wearing revealing clothes etc

i know it’s part of growing up, I had her at 16 so it wasn’t too long ago 😂 but I’m really really struggling with this complete change. She has this horrible attitude that switches from being nice to acting like she’s better than you.

she does absolutely nothing around the house to help etc

she does work Monday - Friday 8am -6pm but is it too much to put her rubbish in the bin?!

Welcome to 18yo teenage girls. Been there, done that. They do come out of it and by 23/25yo will be a normal human being once again.

Oh yes .

im going through this as well . No one warns you!!

you have the impression that at 18 you’re nearly done- wrong !!

teenage girls are fucking awful.

mine is 18.5 and we have had nearly a year of this crap .

not really any major issues until then .

now she’s argumentative, rude and a nightmare to live with.

totally directionless as well - even though she’s had masses of support, and was planning on uni until a month ago.

she does work in a pub a few nights a week (thank goodness)

purposely throwing away a level 3 qualification over a few hours of placement.

im shocked it’s my daughter.

I have no advice- tbh if you discover the answer come back and update us

No innocence lasts.

everyone grows up.

You’ve been incredibly lucky if your dd has only just started with the attitude. Maybe say to her, it’s great she’s enjoying herself. And she’s got a job and being really responsible that way. So you’re really proud of her. And ask her if she thinks the horses should be cared for by her? And what are reasonable expectations for helping around the house? Stuff like that. Ie negotiate, treat her like an adult. You will need to let the tattoo go. She can always remove it at a later date.
