Thanks for sharing and I'm sorry you gotta deal with that 
I've never been good at sharing my feelings for many other reasons on top of it, but not having any kind of emotional support also always hit me pretty hard as well. One of the many great things that's happened to me since realizing I'm trans is both being able to get rid of that shame/mental block around expressing my real self as well as having positive spaces to do it in (thanks tracha!). Correct me if I'm wrong, but it seems to me like even in relatively positive male spaces there's still a lot of discomfort for men around expressing certain feelings openly in the same way. Not sure what it takes to break that, but it at least seems like a good thing to bring up that stuff more often like you're doing right now.
