I know how you feel. I get that feeling of restlessness and stress and I want to fix it but I can't because I don't know what causes it!! Gahh.
The only way I get to ride now that I don't have a horse is riding with friends, or borrowing a friends horse (which, unfourtunaly won't probably happen this summer). I have to drive all the way to my friends house. Her horses are hard to catch, I usually don't get to ride the good one because we can never catch her and her owner is too lazy to try more than like 5 minutes.
So the one I ride is COMPLETELY unaware of my leg cues, they only make the horse go faster :( and usually I have to CONSTANLY pull on his mouth because he wants to go where he wants to go and refuses to walk in the direction I want him to. Then he gets antsy on the way home and WILL NOT stay still, or even walk. Not to brag, but I'm a good rider and still this horse WEARS ME OUT.
But... I don't complain about the horse and riding because its the only way I have to ride and I would pick that dumb horse over not riding ANY DAY.
I got summer hating on me cause I'm hotter than the sun. Win-ter hating on me cause I'm colder than ya'll. I'm being hated by the seasons so forget ya'll who hating for no reason!
