What should i do about this?

Ok, my parents are getting rid of my horse because she is spooky. Now we have another horse but my parents don't really think she is working out either her name is sunny. When we first got sunny i really did not like her because; "she stumbles, she has a ewe neck, 14 is old, shes skinny and has rain rot" but i have been slowly nursing her back to health since early febuary and she is turning into a stunning QH! her coat is shining the rain rot is gone her weight is almost perfect, she hasnt stumbled since her feet were done(they were messed up thats why) her neck has filled in and her withers have to. I realize now how i like her level headed-ness and she is a very nice ride because she is awsome with vocal commands. Im starting to think i should keep her as my horse, what do you think?
