Fatigue and depression

I was just curious about how many of us feel our depression is worse when were fatigued. I can't say mine is necessarily worse but it's a lot harder to look for the positive. I haven't slept well for years. I do use a CPAP machine every night and try to go to bed early enough to "rest" for 7-8 hours a night. Some have offered the idea of relaxtion therapy. Where would I find out about that? My Labor day weekend was just that, LABOR. It was a good use of our time but extremely physical. I spent a great deal of time with my wife, which was enjoyable and we achieved several long desired goals. But on Monday when the work had dwindled down to a one man show, I found myself jealous and envious of my wifes "free time". She had asked me if there was anything she could do to help and I told her no. She asked, I said no, yet I found myself headed in to the dumps because she was "free" to do what ever she wanted. As at turned out she spent a good deal of her time picking up inside while I worked outside. The overlying theme here for me is I'm exhausted seemingly all the time. Even "relaxing" is hard work. What relaxation techniques have ya'll tried? Thanks for reading. Jer
