I have the same sort of trouble that you and many others do. I have found over time that by helping someone else with their problem, no matter what it is, I feel good about myself when it is done. I have fed hungry lonely people, provided and entire Christmas for a needy family and donated clothes and money to fire victims. But it doesn't matter how big the kindness is, I have buttoned a blouse, washed hair and clipped toenails for people who couldn't do it themselves, the result is that for a bit I feel like I have some value. It doesn't last forever but it's a start. Truthfully, the little things are the best. Go to a hospice or an assisted living center and make someone else feel good and you will feel good too. It's a place to start.
