I know what your going through CalmRage. I often feel the same, Don't know if this is right for me or not. Only thing about me, and you might look into this yourself when I am feeling feminine and dressing the part, I feel like I am truly happy. I take care of myself better and look forward to the future. Yes there is times when I feel discouraged and depressed ( yesterday was one of them). When I am in boy mode as in thoughts of being feminine are almost non existent I don't care about anything and anybody I am depressed a lot and can't figure out why. I avoid hanging out with friends , only ones I do hang out with regularly are at work, and just want to be left alone. If I do hang out with friends I am usually not very talkative. In boy mode I remind myself of the main star in "Rules of Engagement"
When I look into myself I realise I know what I want and Know what it will take to be happy. It is a long treacherous rode ahead and there will be alot of times I feel this isn't what I want but deep down I know it to be what I truly want. If I can make it through I feel that then My life will be complete.
As far as you wanting to feel like yourself but in a girls body. You will keep every part of your personality that you wish to keep, nothing will change that except your view on what parts you wish to discard.
