If u had a accident on a horse before don't think about ur accident or al the things that could go wrong. Just focus on the positive things
Since how many time didn't you rode ? I'm riding since I was little but I have found an article about returning back in the saddle how can interest you!
I give you the url: http://www.horsechannel.com/horse-community/5-tips-for-returning-to-riding-as-an-adult.aspx
But personally, I think that the most important is to be lead by a riding instructor !
Good Luck ! 😊
