The only way to feel better is to erase the imaginary hierarchy in your head - there are no people "better" than you - we are all living beings with our own aptitudes - whether somebody is better than maths than you is irrelevant, its a difficult psychology to adopt, but one that will ultimately help you. I have always been academically successful, and people tell me that I am generally intelligent too, and give good advice, and I have seen some people jealous of me in the past, but I feel others have far greater aptitudes than me as well. I would love to be as sociable as some of the people who have been jealous of me, or be able to make as amazing drawings, but I am happy with who I am.
