Confronting your fears is a great way to develop character, my man, well done.
I did the same sort of thing to cure my fear of heights - I went to an indoor climbing centre in Christchurch NZ, and forced myself to go upwards. Actually, the climbing wasn't so hard...(because you are looking up and in front, not down). It was having to let go at the top of the wall (60ft or so I guess, not exactly mountainous, but more than high enough for me, ha) so that you could be belayed down again. Having to put your trust in someone you've only just met, not to drop you into the floor, is intense!.
I also did a series of 3 bungee jumps whilst in NZ. However I missed the first one through timing issues and so had to start with the second jump - the worlds highest (at the time). Talk about a baptism of fire!
Then I capped my 'auto-therapy' of a couple of years later with a skydive. I was shitting myself until I suddenly thought "Today is the day I die." Which oddly brought a wave of calmness over me (I don't fear death apparently) and left me super-chilled. My HR even went down to 44bpm, having a snooze, 20 minutes before the jump.
