Oh hon. Have a big hug.
I'm guessing that you're still at home, where the folks have easy access to you and ability to promote their ideas for you. It takes courage to be yourself. It's far easier to conform, especially when we are trained to. It does not mean that we will be happy or lead fulfilled lives - i can write the book on what not to do, after my 30 odd years of sort-of knowing, but allowing ongoing abuse of my personal boundaries, because they are my parents. As someone safely said to me once, if no one gets hurt in any way, and the law is abided by, then do it. It's far easier to apologise if you have regrets, and if you have none, then be proud of working out a little more of who you are.
What ever you decide, we are here, and do understand.
