I'm still waiting for the "feel good" part of exercising to kick in. Been doing it for years, managed to lose nearly 100 pounds, and still feel like shit whenever I do it and afterwards. I'm at my happiest during the days I don't do any exercise on my days off of work. My therapist doesn't really think much of it since I get enjoyment from other things like frequent theater trips and talking to friends. Like if I could lose weight another way without paying a fuckton for surgery I'd rather do that so I can stay away from the depressed feelings.
