St Johns Wort, 1 tablet per day.
Also, if you can try to get a min of 30mins exercise per day.
This is what my doctor told me. I agree with the exercise, it helps so much. I couldn't take the tablets because i was breast feeding BUT they are supposed to be wonderful.... St johns wort
Bach rescue too. You can get it in drop form to put in your drinks or a spray for in your mouth. They also do a cream which aids healing.
We all get stressed from time to time...
