disappointed beyond discouraged

My adventure with Rohan has come to an end. At the trainer's this week she has fallen into the habit of rearing and flipping whenever she doesnt want to do something, even things she knows already. It has become a full out tantrum over little things and I know there is no way I can get her out of it if a professional can't. So she cannot come back, either my kids or myself will get hurt dealing with her. So it sucks to see all that hard work, time and $ down the drain, and somewhat depressing to see it all fail. Right now it's raining and cant even go play with the good ones I have. Today sucks
