Lay, I can so relate to your situation but the only problem is as positive as you can be it is still horrible to stay in that situation. I just want a job I can go in, have a reasonable day get on with the people I work with and come home, when you have to start playing mind games with people, ignoring them, dealing with them in a certain way it all just gets you down even more, I know it did me.

One place I worked had a lot of the issues you rasied I tried my hardest to think positive and put myself in control and yes it did help a lot but I found the place was getting me so down I was having to go over all my positive thoughts, choices and motivations on a daily basis, my journey there and back home was purey just going over and over these things and that in itself got me down!

The advice given though is excellent but there comes a point where even with this self awareness and positive thought soemtimes all you can do is just leave to make things truely better.
