Thanks for the replies, folks. DEFINITELY something I'm going to bring up with my therapist when I start. 😛
Something else to add, but it's hard to describe: though I feel like I walk through life pretty much emotionally numbed, I feel like there are two distinct modes in my mind, one female and one male. The female side is what I consider my "default", because that's obviously how I was raised, but it's also the one that I consider emotionless, secretly unhappy, etc, despite the fact that she acts to the outside world as happy and outgoing and all that. Then there is a male mode, and I feel like I can turn on this switch to get to him, and as soon as I do that, I actually start feeling emotions and feeling engaged with the world and such.
But I can't keep that mode on without conscious effort, and it's almost like if I was in that mode all the time, it would be such a culture shock because I'd actually be feeling things all the time. It'd be a big change from feeling nothing all the time, though of course I know it's preferable.
