Thank you so much for your replies.
The thing is I tried to fight back when she was laying into me and afterwards I didn't feel anger, just guilt. Guilt as if how dare I feel like this. It's hard for them to get their heads around this situation, obviously. I have been suicidal many times before, off work sick, hospital, even turned to alcohol for long periods (don't drink anymore though) even attempted suicide on several occasions. This isn't something I have looked up on the net a couple of months ago and thought 'ah, that looks like something I can pretend to have to get a few weeks off work'. I got bullied at work, I snapped, got signed off, waiting for the grievance procedure to begin, but now I am getting bullied to go back to the situation that created the problem in the first place. Some people think that depression can be cured by forcing yourself to do things you don't feel you can do. I'm afraid I don't agree with that, the brain needs time to heal so things have to be done in small steps, slowly. Trouble is that makes you look lazy, and people tire of seeing you always miserable. I was in a situation where I got told this at work everyday, but going home wasn't a relief because I got told it at there as well. I told my GP the other day that some people tell me to stop taking my meds, he looked at me very sternly and said 'no, don't, you musn't do that, some people always think they know better, but don't do it, please!'. I assured him I wouldn't.
Anyway, I have calmed down a bit now, that maybe the mirtazapine I have taken (only 1 pill) though. I have a telephone appointment with a psychologist on tuesday and they sent me a form to fill in, one where you score how you have been lately, mine will be quite high!
Can I just say thank you all again for replying, you have probably saved me from doing something stupid.
