A big reason for not moving is the fear that you will be just as unhappy, if not more miserable, in a different situation.

Fear of the unknown, particularly if you have a good imagination, can be crippling. This will in turn make you uncomfortable in your own situation and you will tend to take it out on your workmates. If you don't know from one day to the next how you are going to treat people or how you are going to be treated, then the habit of pre-emptive strikes sets in. Sooner or later, you will strike out just to prevent the very thing that you are creating.

Been there, done that, got the medication.
