How to cope with anxiety in the workplace?

I suffer from depression and anxiety and am working with professionals to find the correct medication for me. However, my anxiety is so high Sunday night in anticipation for going to work on Monday that I feel ill. My thoughts range from wanting to call in sick to quitting my job completely so I won't have to go in. It's not that I hate working, I just get anxious at the thought of being around the people and dealing with them. Is there anything I can do to cope with these thoughts and feelings until my meds get sorted out? please help!
