You're not alone HalfPass.
My Parents never supported my horse passion either, I had to do alot on my own. I learnt how to mow lawns, pull weeds, babysit, house sit, pet sit, walk dogs, wash cars - whatever it was I could do, to make money to ride.
My Parents would never buy me a horse, so I had to Free Lease horses I could get my hands on, which most of the time, that meant backyard, green broke horses - but I got er done.
My Father was born on a very large cattle ranch that was in the family for generations. Built in the early 1800's, where his father was born, and his fathers father..etc, etc, etc.
He was raised that you work from Dawn to Dusk, and if you aren't brining food to the table, you are not a man - and my Mother, being his Wife, supported him.
My Dad said, that horses are a waste of time, you cannot make money riding or being involved with horses and if you got hurt on a horse, that would impede your progress to make and earn money. But yet, I did it on my own.
Now that I live on my own, my Husband is supportive and I have him at least *heart* my Parents still disaprove of my passion for horses. Heck, when Nelson Coliced, my Dad was ready to send money to have him put to sleep - and when he made it through that horrible situation, my Parents were quick to tell me to get rid of him because he's only a burdon financially.
I cannot talk horse at all with them, I cannot share my accomplishments with them when horses are involved - but so be it.
I do not allow that stop me :) You just have to keep doing what you love, and what is right for you and what your soul tells you. If horses make you shine, then so be it. You are around horses for you, no one else. Only you can make that decision, no one else.
I am 33, and still ga-ga over horses and still going strong :)
LOL, I remember growing up, my Parents tried to get my interest in other activities. They put me in Baton Twirling, they put me in Tap Dancing, Bowling, Figure Skating, Ballet, Guitar Lessons, Tennis, Curling - I would give them a go, but I always ended up back with horses :) What can I say? LOL.
You have to do what is right for you - period, end of story. One day, I'll have my own Eventing Facility, my own Students, my own property and then I can say "Nanna nanna boo boo" and shake my butt. :) :)
