I don't know what your situation is, or what your friends are doing. But I suspect if you live your life the way you want to, and find happiness in a healthy relationship, then your friends over time will realise that you are perfect as you are and don't need to change. I would guess they are worried about you, and you need to be strong and persevere and be yourself. When they see you happy being yourself, if they are real friends, then they won't want you any other way.
