Yes, I'm afraid what you describe is about par for us. I felt the same way most of my working life. An antidepressant helps with the stress, the frazzled nerves, etc. If you aren't taking one, see your doctor. You might see about a job at a library or somewhere calmer than fast food. Easier said than done I know but would be worth the effort.
Hang in there my friend.
