Do you have an anxiety disorder or is this an unusual occurrence? I know that extreme stress brings the same for me. I have a job that I am very unhappy in and was facing similar issues before I went to work. For me, I would go for an early morning jog or walk or do some yoga. I also stopped doing things like bringing coffee and breakfast to work and took time in the morning to enjoy those things in quiet without the stress of the office. Small things like that helped very much and has helped me get through my days until I can make a bigger change like a new job
