Try following the de sensitising excerises used in natural horsemanship.  If you can't afford to go to a clinic or the DVDs you can watch how to do it on you tube and on horse and country on sky tv.  Play loads of games from on the ground, get some one to check your riding position, maybe take videos, you can follow your progress that way too.  I did a Dave Stuart clinic, it cost an arm and a leg but since I don't take weekly lessons, it works out actually cheaper.  I lost my nerve after my old horse and I were involved in a car accident.  I wont say I am cured, but things are a hack of a lot more fun these days.  I plan to do a 2nd one with him next year.  You could use bach recue remidy for your self and perhaps your horse needs a magnesium clamer?  Is it him or is it you passing on to him?

start by just working on the ground with him on basics.  try lunging him over jumps if you can and introduce him to different things.  If you scared of riding him try riding an older horse if you can so that you will build up confidence and experience.  if you can't just ride him at the walk until you build up your confidence to work at a trot etc.   If your afraid to ride him approach him and as soon as you feel nervous walk away until you don't then walk back to him as long as it takes until your fear of approaching him goes away.  then if your afraid of riding him tack him up and as soon as you feel afraid walk away as the same as the first.  and do this whenever you feel unconfident.  like mount him then unmount, walk then get off etc.   hope this helps you!

hi,,i was exactly the same and i still havent fully got my confidence back as i was flung thru the wings of a spread . I also have a very spooky horse hus scared of anything i found it helpful to slowly introduce small scary jumps to your pony even on the lunge you dont have to be on your pony and gradually get them to the height of what you were jumping slowly introduce them to yourself aswell making sure you understand were your horses scaredness is coming from and you will be jumping your horse again in no time, good luck :)
