Hey Forgotten child i hear you.
I have a daughter who has been taking drugs for the past 30 years, only drugs seem to matter to her. it looks like she does not even care about herself. take care of you, you are allowed to do that. be careful that you do not start mixing with people who will drain you, they see that you care and take advantage.
love your self for now and heal from your family trauma try to believe in God he can help you.
sending you love. xx
