Changing jobs, living situations, schools etc. are all very natural things to have anxiety about. Though sometimes us folks that suffer from anxiety exasperate those feelings in to an unhealthy state of anxiety.
I can only offer compassion and empathy in regards to that.
I can however offer some insight that can hopefully help you along your way a bit. Never fear who you really are. Never hide, you are special in your uniqueness. If the people around you are not comfortable with who you are then I would say it is time to look for some who are. If you have a hard time showing those emoticons it may be because no one ever showed you how and that seems to be the case with your family. Find some people that share your interests, share your joy or love or grief. When you can honestly share yourself with others you can gain great inner strength.
Good luck with the finals

Namaste
