So... this I just have to write.
On Thursday I returned from a three day trip to Brussels. It was a trip, scheduled by the political party I'm a member of so I was among people of similar persuasion and values. Expected it to be safe, nice and nothing too outside of my comfort zone... boy, was I wrong.
First challenge - blood loss
A few days before takeoff. I get a medical problem - the same one I mention in my testimonial for MHS 5G in the subforum. First time I get this problem for the last two years and this time it was worse than ever.
Even MHS took its sweet time to work. Up until takeoff I wasn't sure I want to take that flight, but I did anyway.
Second challenge - Lack of sleep
One of my biggest fears is to not be able to count on my mind. Not being able to sleep scares the shit out of me and just the night before takeoff I was lying in bed, unable to fall asleep. I was so full of fear I was seriously contemplating not going to Brussels just because of this (and the fact that I usually have trouble falling asleep in a new place).
Meditated a bit, was able to have three hours of sleep and went anyway.
Third challenge - snoring roommate 
To add to the lack of sleep, I had a massively snoring roommate on this trip. I was ready to lose my mind as I pondered the idea I won't get much sleep again. Pushed through it somehow and got a massive 6 hours of sleep amidst all the snoring. Got 4 hours of sleep on the second night.
Fourth challenge - blast from the past
Met an ISFJ girl on the trip, who reminded me a lot of my first (and up to now the only exclusive long-term) girlfriend. I was with my first girlfriend for two years and without going into details we got separated for reasons beyond our control, which was quite painful for me at the time.
Now here's this pretty (and smart) 21-year-old girl, showing me IOIs, butt displays, solid eye contact and smiling all the way. Pushed through a lot of self-hate and feeling sorry for myself (things that were brought up from my past) and made my interest clear in several ways without escalating overtly. We were always with the group, she was an ISFJ anyway so I decided to just keep the sexual and romantic tension in check until we land back in Sofia.
A few hours ago I asked her out for coffee and she was "busy this whole next week". Full stop.
So... I don't think I'm afraid of a lot of stuff in my life, but this trip brought out a lot of crap. Some of my biggest fears were challenged and I went through each one with a deeper sense of inner peace (even if my superficial mind was sometimes freaking the fuck out for a short while).
If I wanted to set up this trip for maximum emotional growth, I can't imagine a much better movie script than this one.
By the way, I forgot my headphones at home so I didn't listen to E2 at all during the trip. I'm in disbelief at the ease, with which I've handled all that.
