Try doing it in an orderly fashion...set aside some time, half an hour let's say, and find a secluded room. Silent, no interruptions...a place where you can easily be present yourself. If you think visually, it might be good to have a notebook. For me, I find it easier to have nothing but myself. Once you are in this place, set a timer, so you won't be tempted to check the clock, and then begin to ask yourself these questions, while being present to nothing but your own thoughts: What gender would you be in a perfect world? Who do you want to be, in a broader sense? What can you do now? What would you like to do?
It might be easy to begin by compiling a list of facts about who you are. Start with your name, age. Then keep listing things that are facts about who you are (and not what your experiences are, or what you judge yourself to be). Personally, I found that approach very effective as I could gradually become more and more present with myself. The most important thing though, and the reason I love this meditative approach, is that you always stay present nd focused on your own thoughts; welcome, don't try to block anything away, but don't invite anything either. Hopefully this doesn't sound like absolute new-age cow excrement, but if you're familiar with meditation you understand what I'm trying to say. Give it a shot-it really has helped me, a lot. Hopefully, it can do the same for you. And one last thing...when you're there looking inwards, don't let yourself feel fear. Fear of yourself is a pointless thing, and an incredibly harmful one.
