18M Australia

Hey everyone I don’t know why I’m posting this but I need to tell someone and who better then strangers, I’m an 18 year old bloke from qld I’m just going to say everything, I’m diagnosed with severe PSTD, severe anxiety, severe depression and I have hallucinations (while completely sober) I am unfortunately using drugs, I’ve lost absolutely everything, every single one of my friends who I’d known for years basically my whole life, I lost my girlfriend who was so incredible, I haven’t spoken to my mum in a year, I haven’t spoken to my twin sisters in about a year and a half and I’ve never really known my dad, I used to run a business I made about 350k from when I was 15-17 I loved my life having come from a “junkie home” I was just for once happy, and it’s all gone, I cannot do this anymore. I seriously just can’t I hate myself, I’m alone, like really alone oh yeah and I might be going to jail, seriously I just want to give up and I don’t see any reason why I shouldn’t anymore
