For me, I think it has to do with my self esteem. I feel like I'm in my 30s now and should have my life figured out. I left a "decent" full time job, only to "fail" at two more when I tried to better myself. I haven't forgiven myself or gotten over leaving the job I originally had. My self esteem is pretty low. So it's kind of a vicious circle. My therapist recommended starting small with a part time job to gain some confidence, and I think I'm gonna try that. I am lucky that the first doctor I found turned out to be very helpful and supportive, and non-judgemental. It sounds like your son is probably experiencing the same issues I am, with self doubt, anxiety and depression. I wish him and you the best! I applaud you for not yelling at him, and supporting him, it can be hard to know what to say, but having people supporting me and not bringing me down further has made a lot of difference!
