I don't think my emotions changed at all.
I suspect a lot of emotional change comes more from self acceptance, being more comfortable in your skin, and coming out from under the burden of dysphoria which is essentially depressing. Also there are often a bunch of other stuff going on when we transition. While I think hormones definitely play a part, emotions are just human things and I think your internal thoughts, comfort with yourself and the expectations from society from whatever gender role you choose to play perhaps have a much bigger impact on how you experience and express emotion than hormones themselves.
Men don't cry in my own culture because my culture says men don't cry, rather than men lacking the ability, emotion or need to cry.
But going back to myself my emotions did not change from taking hormones, at least not that I noticed. But my emotional state definitely changed in response to transitioning, the lessening of dysphoria and feeling more alive than I ever had and perhaps better managing being bi-polar. I would not be so quick to think hormones did this as I think some of us get false expectations about the magic of hormones (they definitely can bring about magical change, but not always and sometimes not to the extent we would like).
