I'm just going to touch on a few things that weren't mentioned since you received such great advise.

1. Try finding a new physical activity to help combat your depression. Try walking, hiking, swimming, yoga, Tai Chi, etc. Would an electronic version of golf, (guessing WII has a version?) be fun? You don't need to play for a prolonged time, just try practicing your swing a few minutes at a time.

2. Consider adopting an animal if you don't have one already that lavishs you with unconditional love. Family and friends are essential of course, but those buggers are complicated. I can't begin to tell you how much the quality of my life has improved since I adopted my fur-baby. She knows when I'm dealing with a flare and just cuddles up, and she knows when I'm just being lazy, and forces me to take her on longer walks.

3. Learning to adapt is not easy, but you will.

4. If you can afford it, go on a vacation. Somewhere tropical where you can swim in warm water preferably! Even doing a weekend trip to somewhere close can really help. (And we can help with all the tricks to manage traveling as well.)
