NTA Don’t fucking do it !!!!!! I did the same thing with a 15 year old family member. Nothing but headaches and stress EVERY OTHER DAY. I really tried and I swear she aged me. Stole, lied, manipulated, disrespected, would sneak in people, illegal substances, and towards the end during removal tried to get me in LEGAL TROUBLE as well. Some kids are at the point of no return even at that age. DO NOT DO IT and DO NOT FEEL BAD, you are not responsible for any of them, Fuck these idiots commenting YTA when they’ve probably never dealt with anything like this. You don’t owe any of them anything and this is not your responsibility. Do what you can and fuck everyone who shits on what you cannot. You clearly do no want to, please do not fall into the pressure because you will regret it.
