So what? They don't own you. YOU own you. The very best thing you can do for YOU is become stronger, more confident, build your self-esteem, look better, feel better, be healthier and have goals. What in that sounds like a negative for you????
The only reason someone wouldn't support your goals is because you might just realize you're strong enough to take care of yourself, BY yourself. You approve of yourself enough that you don't require THEIR approval. That's scary shit. For them.
When all else fails, you have me. And that's pretty damn awesome.
