I think that T has made it very difficult for me to cry, but my experience COULD be explained by steadily increasing happiness.
Still, I don't think so. Or it's a combination of factors. Before T, I cried a lot. After T, no.
When my ex broke up with me a couple of months ago, I sure as heck didn't cry, and I still haven't. He's had a few episodes of extremely mean and petty behavior since then--he's not an a$$hole generally, but it does happen when he's very very stressed--that normally would have made me cry. Nothing.
When I was remembering some particularly painful memories, I sort of leaked around the edges, but I didn't really cry.
A few times, I have felt very low and actually wanted to cry. On one occasion, I knew that I really needed to let go, so I spent a few hours getting in touch with my feelings and was finally able to cry all out. It was hard, and I had to work at it. All the other times, I only experienced a little bit of that "leakage" that I talked about--a couple of tears and that's it.
I did have one particularly traumatic thing happen that made me cry a little, but I wonder if I would have really let loose if I weren't on T.
I have been steadily becoming happier and more confident, though. So that is probably an influence. But I have read about research studies that claim that T makes it harder to cry. I don't know how accurate these studies are--you would have to poke around a bit and find out.
