Wouldn't it be great if we could just "zap" all of our anxiety away and have it be gone? Or better yet, if we could somehow take all that nervous energy and turn in around and make it work for us instead of holding us back, we'd really be able to excel!

What I think I'm hearing in your story is that the money you make by working at the pizza shop isn't enough of a motivator to overcome either your anxiety or your lack of desire to give up your free time. Understandable. So, a job in a field of interest may provide the additional incentive needed to move you past this block. You say working with the mentally handicapped is appealing to you but are afraid of having this same emotional response to it. Why don't you try volunteering first? This would enable you to "try it out" and see if you like it. Volunteering has few strings attached, and if you do like it, then you could see about getting a job.

Also, you say your parents have both been at their jobs a long time. As a result, they may not be able to relate to your current feelings and thoughts about your job, but almost everyone has felt anxiety at some point in their lives. I encourage you to share how you feel with them. Their support in helping you deal with this and finding solutions would be really beneficial!
