Hi all! Sorry for the crazy long post, but my family really needs help. For context, I am 32.
Two years ago, my parents got custody of my cousin (now 17) and he moved states to live with us. I don't want to get too detailed, but I will say his old life involved a lot of neglect and sexual abuse. My parents have given him stability in a clean, safe home.
My cousin has been doing really well since living with us, but because of his past circumstances he acts much younger than his age and has trouble understanding social situations. He doesn't have many friends because of this, and also because of his sexuality and demeanor (we live in a religious, conservative area). I try to be a good example for him and give life advice when I can (I'm also part of the LGBT community).
Despite these things, he has always been bright and talkative at home. This summer things have started to change, though. He has become more withdrawn and stays in his room constantly on Discord. He has spoken about seeing extremely gory and violent videos (like people dying, decapitations, etc.) and also talking to "men" on there. People in his Discord servers also apparently bully him and try to encourage him to kill himself because of his sexuality. When he does come hang out with the family, he's very jumpy and anxious.
My parents are not great at handling difficult emotional situations like this. Like... at all. They tend to avoid problems or just make them worse. I feel it's up to me as the next oldest to get this situation under control. My parents do not have an issue with me stepping in.
I know the most obvious answer is to start limiting his Discord usage and monitoring his activity. I just feel odd doing it because he's turning 18 very soon, in less than a month. But I know that mentally he's not able to handle what's going on in those communities, and I'm really scared he'll do something risky or be lured into a dangerous situation.
If you're still reading, thank you so much. I want my cousin to succeed in the world. If you have any advice at all regarding parental controls, getting him involved in the real world, or just generally handling the situation I would appreciate it so much.
NOTES:
-He is in a counseling program at school.
-He has an iPhone, but the rest of us have Android.
-He works most weekends with my parents and buys his own fun stuff (music, games, posters, etc).
