First things first Jenice, suicide is NOT the answer. You still have a fiance, and a family - even if things with them are not going particularly well right now. So keep that thought out of your head - nothing good would come from killing yourself and some people believe it'll be much worse on the other side.

Now, aside from that the other advice you've gotten so far is appropriate. You may just have to look for other jobs outside of what you've been trained to do. I know it's tough, and you may have to settle for a little less pay but personally I've never been able to work in environments like the one you've described. I had a job up in Trenton before that was very damaging to be emotionally due to my relationships with co-workers and even the boss. I left for another job where I've had a bit of a paycut but it was worth it to be in a better environment. i wish you the best in whatever you do. And this article, by the way, may be of some help to you.
