People with anxiety problem can try to have enough sleep, about 7 to 8 hours everyday. Then, the next morning having a cup of Milo or coffee, and biscuits or bread to get carbohydrate and energy. This helps the brain to stay alert and healthy. I have tried to drink coffee every morning, and it does help me to stay focus on the work, although sometimes I do have some mental stress.

Besides that, you can try to find job that you are really interested at, so that when you are busy for working, you will feel satisfied and happy. Work life balance is also important. I think this can help to alleviate the anxiety burden.
