I'm not really enjoying life. I have no friends, no girlfriend, no real hobbies and lack of care for anything. I don't have motivation for anything anymore. Im not sad, I'm either pissed to the point were I could rip someones head off or i have no emotion at all. Summer break has begun and all I've been doing is sitting inside watching youtube or playing Sonic Mania on my switch and work a couple of days in the evening. 

2 days ago it was 38°c (100°f) outside and the only times i went outside was to go to the dentist and walk my dog. Idk what to do with my life really. People have given me alot of suggestions on what i could do but nothing interests me. I want to do something but where do i start if i don't even have the motivation for anything?
