big hug to you, though I'm a bit late. I had the same thing going on a few months ago, my coworkers made the environment unbarable for me and of course it was intentional. Because of all that stress I went out and found a job which I absolutely love and not to mention it pays a bit better

maybe it is just time to leave your old job behind and search for something that will make you happier in the long run. Whatever you do, do not beat yourself up over these circumstances, eventually it will all clear up for you. keeping you in my prayers and wishing you all the best.
