Okay so I’ve been reading online for symptoms of depression or anxiety but because it’s the internet I don’t know if I can believe it. And I’m hoping y’all can help me out??

What are the symptoms? Cuz often I feel like killing my self and by the next hour I’m fine and don’t know why I even thought that. I’m constantly hating to interact with people, to point where I get so mad that I’ll just cry and think how my life sucks. I really just don’t know what I want anymore or even who I am. And if y’all think maybe I have some signs I’ll see if I can see a therapist or someone to talk to

The whole killing self comes up more often then but disappears by and hour or so later. And I hate that I do this I just don’t know what I’m supposed to do anymore.
