Don't worry Blackdove, you will eventually be able to cry. I couldn't cry for the first two or three years of therapy (for about the first year I could barely talk either). I don't know why not, but there were just no tears there and everything felt numb and detached. Then when I started crying I couldn't stop for quite a while, and would cry all session even though I couldn't always pinpoint exactly what I was crying about. But it was nice to have a place where I could go and just cry and not have to hide it or make up some sort of excuse for why I was crying. And it felt like a move in the right direction.
I still cry quite a lot. Sometimes I cry for no obvious reason, I just feel like crying, so I have a bawl and then I feel a little better. Sometimes I go for a while without crying. I guess we're all different, but for me, being able to start crying was a positive thing.
Best wishes,
