Awwww, it is terrible to not be accepted by those people you love the most. You would expect people to accept who you are, and even accept you.

The reality is ... some people don't understand. Since they don't understand, it will be hard for them to accept you.

Instead of focusing on them, focus on you. Do what makes you happy. Accept the fact that you exist for yourself, not for them. Love your positive traits, and love your flaws too. In the end, what matters is how you feel about yourself.
