I used to get a lot of anxiety before going to work. It was hard, and I guess what has made it better is me becoming more at ease with myself and generally combating my anxiety on all fronts. I'm immensely grateful towards my earlier self for persisting though, because without the experiences I had and the opportunities it gave me I wouldn't be in the place I'm in right now. I recommend that you try to analyze what you dislike most about your job, and what concerns are due to your anxiety, and what problems would be legitimate grievances for anyone. For example, I thought it was painful to have to talk to my co-workers and customers. That's hardly reasonable and something you will have to face. If that's what makes you suffer you should try to face it, as running away will only make the fear worse. However I also had a quite bad boss and the mood around the workplace wasn't very good. This is bad for anyone, and if things like these are your main concerns, you should look for another job. Dealing with your anxiety is hard enough without having to deal with other kinds of crap, so avoid that if you can.
