Replying to Backflip Help

So I got a new tramp this summer, and I am landing backflips very consistently and have no fear at all. Yesterday I began to try them on the ground. It went very well and I was commiting to the flip everytime and getting pretty close to landing them. Then on one attempt I didn't commit and bailed halfway. I wasn't hurt at all and the fall didn't scare me, but I can't get myself to do another flat ground flip. Any tips on how I can get rid of this fear or should I just start on the tramp again.
