You are under stress if everything that you do throughout the day brings to you a sense of nausea and helplessness. Every job seems a chore that you just have to go through without having any choice in the matter.
You need to seriously examine all aspects of your life and job. Are you in a loveless marriage or are you in a dead end job. Examine your life in detail and do something to bring some change into your life, even if it means visiting a counselor or just looking for another job.
