I admire your resolve to overcome this and continue to participate in this wonderful sport. Just stick with it and your will get past the trauma and love riding again.
Two years ago I took a nasty fall off of my skis and broke my collarbone. I have a long and injury plagued athletic career and I didn't think that I was mentally affected by the fall and injury at all. The following winter I did not get to ski just due to life. When I went this past winter I was skiing very tentatively. My husband recognized it but didn't say anything for fear that it would make me self consious and therefore make my skiing even worse. On day 3 of our trip i told him I needed to take a lesson to get past this and only then did he tell me that he had noticed my lack of confidence as well. I spent a half a day with a female instructor and it was like night and day. The rest of the trip was like old times.
Give it time, get help when you need it and it will come back.
