gee, some of what you said sound kinda like trying to express an opinion on how you feel about something on this forum
seriously, it is your life...if you are just intrerested in positive, creative, fulfilling things than you cannot let others stand in your way.
it is hard to not have not only the support but the validation of those we care about with our decisions.
i have had that problem myself and while difficult, i have tried to remain true to myself as much as possible.
sometimes we are ever changing, i know i am, and while intially i may be hurt by the surprise of a new self i may project not being immediately accepted...i find when other people realize this is you and it is making you happy, they will get use to it too.
