[Dancer for life]

I just started high school about halfway through last year bc I was ahead in middle school so that meant new friends. I made 2 new friends one that I'm still talking to so its fine. But my other friend I made we were talking and hangout for the first week of summer but then he just started ignoring me he got grounded and his mom texted me to tell me that and when he got his phone back I texted him and said hi then he said brb and hasn't texted me in weeks. Idk if he got tired of me bc I get depressed a lot or if he got mad at me bc he might have found out about me hurting myself again idk what happened he sees my messages on Instagram and when I text him it says he's read them but he ignores them school is about to start in a week and I wanna talk to him about it when I go back but I don't know if I should even talk to him what if he gets mad at me for talking to him I'm just so confused about what I'm supposed to do and I'm already hating the thought of going back to school bc of this he won't even tell me what I've done to make him ignore me idk if this is all out of order I'm
Sorry
