I think I've hit rock bottom again

I feel absolutely horrible. I can't seem to connect with anyone, I feel so alone in this world. The only things that really give me enjoyment are cigarettes and fashion. But the enjoyment of buying a new hat fades away the second I pay for it. My therapist is a low life who doesn't seem to know how to help me. My worldview is too distorted to actually find enjoyment in most things. I don't wanna continue living if this is all there is to life. Humans are filthy, disgusting animals... I don't wanna live be a part of this species. My suicidal thoughts also seem to have spiked recently. And they're more gruesome than ever. Cutting off of fingers because I'm not worth it, severing of limbs to die in my own blood... It's horrid, but gives me some peace.

Please help, I hate this world, what can I do, if anything at all?
