Hi. I know this is an older thread but reading your post was like reading my life. I quit working 5 years ago due to my Bipolar and drug abuse problems. I am now on permanent social security. I feel totally worthless inside. At least when I worked I felt I had a purpose. Now I feel like I don't belong to anything or anywhere. I've been told I should volunteer. I guess that would help me, I just don't have the motivation to do it. I feel stuck.
