I would work on trying to make a few friends by joining a hobby group or volunteering for some cause you would like to support; it sounds like you have been spending a lot of your life trying to please other people. If possible I'd move a hobby, or friend's connections or volunteer job into a real job that was slower paced and something you really enjoyed. I would make a little 5-year plan for myself, to get me to retirement, kind of like one makes a plan for schooling, etc. I found this book extremely helpful (I'm 61):
