Good job!
I had a similar experience with exposure today (though it wasn't intentional exposure). It was my sister's birthday so everyone went out to dinner at a restaurant. A few years ago I'd avoid restaurants like the plague, but now I force myself to go, not only because I enjoy my family's company and they enjoy mine, but because it's good for me. When we got to the place, it was surprisingly crowded, so my 'anxiety instinct' kicked in, with thoughts such as people judging me for this and that, or thinking something negative whenever someone looked at me, etc. The reason why these thoughts were harmless is because I immediately removed their power upon arrival, and so they were just words going through my mind. All in all, despite all the people, I didn't really care about that aspect of the evening and just enjoyed my meal without the troubles of excessive sweating, or blushing/flushing, shaky hands, eyes all over the place, shy speech, etc.
It feels good to have a proper experience and go past all the "oh poor me, I think people are judging me negatively" thing, which gets old very fast.
