You are correct it is better to be away from work when you have severe depression. Trying to stay or go back would probably only push you down more. I speak from experience. Had a major problem at work which wore me down to the point of being suicidal and needing to go to a psychiatric ward. Do you have a way to retire on disability in Canada? You may need to do this because once you have burned out and become severely depressed it may take more than six months to recuperate. It has been two years for me now and I am still prone to bad memories. Take it easy and do what you need to do to maintain your life. The others here are correct do not let your daughter get you down. You deserve a lot of respect in fighting your problem at work, and nothing is wrong in saying you can not do it anymore.
