Yeah, when I finally wrapped my head around the fact that I can do this--transition, be a man physically, drop the fantasies and wishing and just make it real--it was hell. My coping mechanism was really convoluted or so I thought--I'm really surprised & glad to see that I'm not the only one who pictured myself as physically male way before even realizing that I could transition (for too many years I thought that only MTF transitioning was possible, because that's all that I was ever exposed to or heard of).
In my head, it got to the point that I thought that maybe, just maybe, other people saw what I saw in myself. That ended abruptly when I finally realized that this is not, nor ever was, the case; it was awful having my only coping mechanism go out from under me. I felt like a fool for thinking that others could see me for what I am, when in reality they were attracted to what they and the rest of the world saw--a small female, hidden perhaps under layers of clothing and black and aggression, but still undeniably 'girl' and 'cute.' I was invisible and I couldn't handle it anymore. So now my coping mechanism has become moving forward with transition, slow as that process might be. I still do a bit of dissociation, though now it's more seeing the potential that this female body has for becoming male. It's short but otherwise not that bad (the whole 'can't have a proper penis' thing still gnaws on my mind though... really wish there were better options for that). Anyways, best wishes to you for getting through this rough patch; take 'er easy, dude.
