There are two things to consider with the horse. 1, it can take time to bond with your horse and love her. 2, not all horses are meant for all people, so it IS possible she is not the horse for you, in which case selling her and trying to find another (taking your time) would be in your AND her best interest.
Also sounds like you do not enjoy this barn, so I'd look for another. I'm sure there are many more options out there than you realize, the trick is in finding them ;) Go to a barrel race, and ask people there where they board their horses, then go check those places out.
