i want you to know i feel the same way at times.
i can give you some advise of what i do and it sounds weird but write everything down. write on paper!explain everything you see hear, how you hear it. be as graphic as you can. then when you feel like you have a break either go outside or in a sink and burn the paper.
to me it is a symbol of getting it out of me.
i know it sounds weird and it may take a couple of times but it works for me.
that is the only advise i can give, because truthfully i dont know what else to do.
