Scared to ride my horse out of the paddock?

well if she is too much for you why did you buy her? and she might playing up when you go near the barn to try and get out of doing work. I wouldn't worry about her running around the paddock, she's just playing with the other horses, and getting rid of energy, do you have a arena to ride in?, if you do or really anywhere enclosed, do some lunging to let her get rid of excess energy, then ride her, and it might be helpful to get a trainer if you're really scared to ride her. GOODLUCK! :D
