idk what goes here

I don't know what to do, I keep getting sad randomly and it hurts me so badly to the point where I feel like I can't function and I just self-isolate myself to where as soon as my dad or someone tries to talk to me, I'm mute. I need help. I don't know what to do and I don't want to relapse again. My normal daily life is bad, but that doesn't matter. i can't handle this anymore it fvcking hurts. I wish someone was here for me but no, here I am talking on here because nobody else will listen.
