Stuck in a rut

Finding myself in a bit of an awkward situation at the moment although i am enjoying my college course i am finding it really hard to work with girls who our either younger then me or have a mental age of 15! And my passion for photography is so much stronger then it is for make-up i just want to concentrate on my photography more then make-up. I know everyone keeps telling me to keep my head up and not listen to them, but for someone who has struggled with there issue with there weight for most her life it is so hard to ignore when comments are made. I just feel very un-happy at college but enjoy the course when we learn new things what to do!?
