That's definitely frustrating. Do you know of anyone that has a healthy horse you could catch ride for rodeo while your two are getting sorted out?
Or maybe a friend has an extra horse you could ride for a bit?
Definitely sucks that your best friend moved away, but it sounds like you have other friends to spend time with too! Just keep trying to be positive and look for ways to get around the lack of horse issue. Good luck!
