Have you seeked help from a psychologist to help you cope of your depression?
I've suffered from mild depression and at times severe depression throughout my life. I don't believe in medication and I've found that finding the root of the problem has helped me cope with it.
I'm not sure if you believe in God, but for me, believing that God will take care of things that are out of my control and that I'm ok the way I am now has helped me tremendously.
My biggest source for depression is feeling that I'm not living up to my expectations, which are very irrational and based on what I see around me. For example: I may be depressed if I don't have the social life others have, or if I'm not the perfect mom I should be. It was until I accepted myself to be ok with what I am and what I have accomplished when started feeling better.
It is a day to day battle but I'm much better than I was 10 years ago. There are days when I have to force myself to move around or do things even when I'm feeling a great sense of sadness so I need to focus on just getting to the end of the day.
Another thing that helped me was focusing on the moment and forgetting about what would happen tomorrow. There are times I have to on just one hour at a time.
Hope this helps.. :-)
