I'm not sure which forum this should be in. I thought maybe dealing with emotions was best.

I'm a musician who suffers from low self-esteem, anxiety, and depression. I had been in contact within the last few years with a professional musician who teaches private lessons. We have chatted a few times about setting up a time to meet / schedule lessons. It hasn't happened yet, but I'm hopeful eventually it will.

I just saw a video of an old classmate and this teacher playing together. They seemed to be having fun and classmate seems to have expanded their musical horizons by learning from this teacher.

I am struggling with disappointment and jealously. I am not sure how to reconcile this feeling within myself. I feel that I should be the one in that video, not my friend/classmate. How do people with low self-esteem tell themselves that it's OK that someone else is better / more accomplished than they are? I am really having a hard time with life lately.
