How would someone know if they have this? I've only had consistent treatment for depression for 5 or 6 years, but it went off the rails again after a gastric bypass that I had 2 years ago. Nothing I have done since the surgery has helped except for just a few minutes or hours. Like if I go out somewhere it helps until I leave that place to go back home. If I find a program on TV I like or use to like it only helps for a few minutes then I'm depressed again. I feel like I'm in a rut and can't get out. What has everyone else done that has helped?
