Hi i don't even know what to do anymore.

I'm really depressed. Like, is chronic. It feels like I'm bleeding out and nobody is doing anything, not even myself. I feel stuck, as if I'm drowning in the same day that keeps repeating itself over and over. I genuinely can't take it anymore. I feel sick, disgusting even. I've tried therapy and everything related to it, you know, professional help. My mother is supportive too. So i dont know whats fucking wrong with me. I feel alone in a dark hole wich i can't scape, AND lately Is just worse. I feel psychotic. Completely insane. It feels like someone or something other than me is living in my head, like a demon or something. It tells me things I can't understand i don't know why It wont go away. I really just need to talk to someone who's depressed too. I feel like it's something you can't explain if you haven't felt it before.
