I thought things had been going better since I've been back from holiday, but everything seems to be falling to pieces again.

My line manager asked me to have a word with her today and basically said that my behaviour is immature, that I'm oversensitive and that I'm disrupting the service / the team etc. She tried to be nice and 'constructive' in the end and tried to say some positive things about me and my work, but I felt so upset.

I had written her an email and I think I was within my rights to write it. Basically, I said that I didn't like it when she said to me in a certain context "Have you got a brain?" and I put it as politely as possible. I explained that it's hurtful and that I wouldn't say such a thing etc. She was furious and said that I should stop writing emails like this, that there's a lot of time spent on me being upset and sorting this out, that the world doesn't revolve around me and that I am in tears so often and upset / disrupt the others. Besides, I'm not really working within the team properly etc. Yes, she tried to be nice and understanding later and maybe a lot of the things are my fault, but the whole thing has shaken me up so badly I can't really cope with it.

I just want a way out of all this.

This is not all. There are other things like disappointments about personal things, but the work situation is right now completely bad.

I don't know what to do any longer. I just can't cope with this any longer.
If I'm immature so be it. If I'm disruptive or oversensitive ... well. I just wish I'd never have to back there again. I just wish I would wake up and everything had just been a bad dream and none of that is real.

If I hand in my notice on Monday, I will not only lose my job and income, I will also lose my accommodation, because the accommodation is tied to my workplace and I can't live there any longer after leaving.

I feel desperate. Am I just rubbish and a burden and problem to others?
