I have a switch I flip emotions cut off
What do you mean when you say you have a switch?
I'm a schizophrenic, I have misophonia towards my mother, I intended to kill my mother when I was 12.
It sounds like you're bottling up a lot of negative emotions, which can be really unhealthy for you given your condition.  You should speak to your therapist!
I was but she isn't helping me at all.
I think that you should find another one to speak to. It can be so hard to keep emotions bottled up like that, as they will all spill out eventually.
