Work Place Anxiety Help?

I have recently started suffering from anxiety due to several factors in my life but now have this under control in some areas of my life but not my working life. Every time i go to work i feel totally inferior and anxious. I know my boss has lost credibility with me due to a unforeseen incident that happened which i took the rap for but did not commit. I feel scrutinized and judged by my other work colleagues and when my boss is present i get really nervous and panic about what i am doing and start stressing if i am doing it right. The other work colleagues get along fine with the boss where i feel excluded and more like the 3rd wheel the other day i discovered a list of things that were about my work performance that were really only minor but enough for me to feel really anxious to the point i had to take time off work to get myself back on track and think things through any suggestions to help or ideas on how to overcome this issue would be great.
