Have you tried Celexa? I am not sure if that is how it is spelled. I am going to give it a shot. Everyone that I know is taking it for depression. They call them their happy pills.
It can be really hard when you are someplace where you don't have a support system. My mom is in a place with really no family members left. She went out and joined clubs, groups, just to get out. There are people of all ages, incomes, and backgrounds out there. Our paper publishes a page with lots of different groups to join or volunteer opportunities. The lunch buddy and or the reading to kids programs work well for getting out, meeting people and getting to be around kids. It only takes one hour, as many times a week as you like, and it is great for taking your mind off of the pain for an hour. It is amazing how working with kids takes you away from the pain.
These boards are a great support group. It allows you to talk to people with like problems.
I walk for depression and lay in the sun for fifteen minutes a day. I bundle up and go out no matter what. If I can just get sun on my head for fifteen minutes, it is better than before.
