I was raised in a conservative family in which any kind of emotional behavior was considered unseemly. Anger, sadness, fear, grief, pride, it didn't matter. Because of this (and because of other factors, like having the deep dark secret of being trans), I've always kept my feelings in check as much as possible, all my life. Then I finally realized that crying is a healthy outlet, and BANG, it was gone for months, at a terrible time in my life when I was under tremendous pressure and really needed to let it all out. I could get into my car, drive down the freeway, and yell in fury at the top of my lungs, but the crying just dried up.
I still felt the misery, the grief, the fear, but I lost the ability to express it in a particular way. I found it very easy to channel it all into anger, however, and to express that anger.
I am convinced that the T was responsible.
