Every so often, maybe once a month or so, I go into this odd state. I kind of emotionally flatline- I don't feel anything, I don't respond to anything, I have flat affect in conversation (of which there is very little) and my facial features feel like they're made of stone. If I attempt to smile it feels unnatural and strange. I also don't make eye contact at all. I am antisocial and hate being around anyone, I don't even want them to look at me. I can't stand being touched. I feel heavy and like I'm moving extremely slowly and mostly just lay in bed on my computer.

These are all phobias of mine, but during this time they have this disturbing sense of comfort to them. I generally mostly believe that I am dead. This sometimes leads to self harm, other times it staves it off because I'm already dead, what more can I do?

I'm told these are depression related.

Anxiety and depression can lead to depersonalization and dissociation.
