I know the feeling. I had three bad falls in a row - one from a bucking colt, one (complete accident) from my trustworthy mare while running poles which broke my arm in a bad way, and then again (while I was trying to regain my confidence from the previous accident) from my older mare who bucked me off. I truly believe she bucked due to uncomfort in her bride. She had been tossing her head that day. Either way, my confidence was pretty shook up! And, as fear works in mysterious ways, I can still ride my older mare and the naughty pony but would have a nervous brake down when attempting to get on my colt - who logically speaking will probably never buck. I've slowing been getting over my fear. It took my best friend just about forcing me to get on and then not let me off again until I could sit on him calmly. He of course, could care less. He was just happy to be hanging out with me.
I guess my point is, fear stinks but you will ride again! Personally, I think if you can't be relaxed on your horse, you are not ready to get back on. Your fear will transfer to your horse and make him fearful. He looks to you as a leader and if you can't lead in the saddle, keep leading on the ground until you're ready.
Don't squat with yer spurs on!
