Welcome Breezy,
Bonsai and fmf have got the Awake for you with the quote. This is really good to use with your parents. They seem reasonable and balanced as they did not encourage pre teen or teen baptism for you, I think they will eventually accept your religious position.
If you show them you can be morally upright and responsible, I am sure they won't shun you as you're not baptised.
Good luck and keep us informed
