Since you know that you won't get the supportive reaction you want, I would stop bringing up these things with your family. It would be better to find friends or professionals who are more willing to hear you out on these matters.

I know that as I get older, I find that it is just easier to share less with my parents. They will always have an opinion about what they think their kid should do/be like. A friend doesn't have that same judgment laden attitude.
