Always tuff dealing with work related stress but, if you can find confidence and peace with yourself first AND confidence in your work, see if you can find the source causing the work related stress. Can you go to that source and and try working it out; talking about how to solve the issue(s).
Be positive and good luck :)
Is it stress from just the job itself or someone causing it? I noticed you stated 'anger' so that's why I ask. I had that situation with someone who caused all kinds of bad stuff in the office. I was severely stressed for about 2 years and it started affecting my health. I had a miscarriage due to it and bowel issues, etc. I eventually quit. Anyways...if it is someone or something in your work area that can be dealt with then that is hopeful. If it's just the job itself, your anger/stress will only get worse ;<
