Hi and welcome. It's always so encouraging when a young person finds the courage to question dogma while they still have all their life ahead of them. Your opportunities are endless.
There is a forum member here who started training a lot older than you are and he is now a qualified emergency doctor saving lives every day. Look out for posts from 'Snare & Racket'.
Follow your dreams. Start planning now. Aim high.
If you have questions or concerns about doctrine or faith or dealing with pressure from family we have lots of experience to offer.
