In all honesty you have to do what is right for you, even IF someone is dissapointed in you, that is not your problem. Have you have heard the quote, "What others think of you is none of your business."? Also, find like-minded people who DO appreciate and support you. Join a club that revolves around a hobby, read, volunteer, find out what you are really passionate about and just do it!! :DTake some time for yourself to figure out specifically why you are so sad. Talk to anyone you feel you can trust and be honest with them about how you feel. Anyone who really cares will listen and support you.I've been feeling a lot of anxiety and sadness and such too, but I am taking steps to lessen that and talk with people who support me, including a counselor.
