Sorry you had that experience, I would agree that realluy was a run of bad luck. In my experience, getting back on and riding out the nerves is the best thing one can do. However, if you are already uncomfortable....which is totally reasonable considering your ordeal, try working in a roundpen or fenced arena, then move gradually to bigger area. Also, finding a friend to keep you accountable to riding with purpose and not FEAR is really helpful. This is also helpful in that you have someone to spot you if for some reason another incident occured. Good Luck, just remember to ride it out.
