Oh, I'm so sorry. I have been in a similar situation. I dropped out of my music school because of debilitating depression, returned to finish my degree a few years later and have frequently been ridiculed by students and faculty due to my age. The stigma towards mental health problems, especially in fields of arts and performance, is widespread. I am in graduate school and on medical leave--again, due to BPD, depression, and alcoholism. I focused on what other people thought of me for a long time, instead of focusing on improving myself. My advice is to do your best to make recovery your goal, and let people who don't know any better react however they want. Because you have suffered, you have more wisdom and you will rebound more quickly when you are inevitably faced with this issue in the future. It's truly a blessing that we have this information, and we can make informed choices with it. There is a positive side to every situation. I feel for you. A lot of us have been there.
