Gee. Sounds like you are worrying quite a bit. Just be prepared in case your family has the reaction you are afraid of, but also be open to things going better than you expected. And take it slow. Don't do anything you don't feel ready for.
Just keep working at making your life one you can be proud of for yourself. You can't do more than that.
Never linger too long with the ignorant,
throw stones at their talk.
Walk only with the lovers,
the mirror of the soul gets rusty when
dipped in muddy water.
