I have a lot of the same things to say. Overall, I think that my emotions in general are more muted--which does not mean "robotic" or "soulless," it just means that they aren't subject to the sparklefire peaks or horrifying abysses that I used to experience. Within about six hours of my shot, especially, I feel really, really chill for awhile. Frankly, I don't miss the higher highs that much, and every time my levels dip and I get a glimpse of what it used to be like to feel fear, pain, and sorrow, I'm glad to be done with it. I'll take a smaller range and a steadier helm, as it were.
Pain is a different story for me now, too. Really horrible serious pain is still as bad, of course (my nurse declined to bring me my pain medication on time once while I was recovering from hysto, and I bawled like an infant) but if we're talking about everyday, banged-your-shin-on-the-coffee-table pain, it has much less of an emotional effect. For the first time in my life, pain was only pain, and a late-night coffee table mishap didn't make me tear up like my best friend just slapped me in the face.
The thing about crying is true for some people. One day when I had had a bad, dysphoric day a few months after I started T, I came home and decided to just cry in my bedroom to get the feelings out and be done with it. But...it just wasn't in the drop-down menu anymore. I tried for a few minutes, profoundly puzzled, but it was like trying to hiccup on purpose. I sat there going "Hnnnnhh....hnnnnnnnnh" for a bit and then I was like, well, s***, what do I do now? Turned out that physical exercise was helpful, as was writing my feelings down, which used to just make me angrier/sadder/more whatever-bad-feeling. Finding ways of coping with it is an individual thing, though, and some guys seem to still have good access to crying when they want to. Note that I started on a much lower dose of T than is standard, so you may get this even if you go low and slow.
I have not noticed increased aggression. Transition on the whole enabled me to let go of a lot of my rage toward the world in general, and it seems to be easier to say "whatever, f*** you" when I'm cut off in traffic and forget it instead of steaming for hours.
