I'm so sorry that you've had to deal with all of that!!!
If it's any consolation, my first boarding experience was crappy too - - but, you pack up, move your toys and move on
I wish you luck in selling Gypsy - and I hope that you are able to get Taxi
Just know that not every horse person is like that! And about the "star kid" thing, every low-end boarding place that I've been to that has a trainer makes the "star kid" feel special because that's
the kid they feel they can sucker their parent's into buying anything
(like the saddle, or a "super duper horse" that's crap, or the really fancy attire)...none of it is needed, but it is money going into the trainer's pocket
(not supposed to make you feel better, but it's a fact!)
Just remember why you got into horses...and strive to make every trip out to your current place and with Gypsy a good one. So she spooks...invent games that are safe for you that introduce her to all sorts of spooky stuff. Don't want to do that? Have a groom day, or a lunge day, or a trail day, or a "hey would you ride my horse" day. Make it fun for you.
You're not paying all of those bills for you to feel like crap. So don't let them!!!
Think about this: what effect are you going to let them have on your life in the long run? Do you want to look back 5-10 years from now and say "well, it was really bad there so I just got out of horses all together" or would you want to say "Ha! I remember that crappy place...sure am glad I got out of there (as you are celebrating your latest show victory on a horse you've put lots of time in) "
Sometimes a move or change of pace is exactly what you need.
