The balancing act you are now required to display is tough for anyone. There were some pretty hairy times with my family as I was learning to question things--and you will have to decide when to be silent and when to speak up. I don't think it's ever easy to know WHEN to do WHAT. We really care for you here on this site and we want you to be successful, so we give advice in hopes that you can endure this without too much bitterness and resentment toward your family. You are on the right track. Just forgive yourself when you think you've overstepped and give yourself a pat on the back at the same time!
Your burden is a wonderful one--at least you KNOW now, and your mind is not under someone else's control. You KNOW! They are misguided loved ones who think that they know what's best for you...be gentle with them as you can. They can never take away what you already know. Best of luck to ya, Kid48.
