So long ago, before it was possible to legally "transition" and when SRS was out of reach for all except the very wealthy, was the blackest time of my life. The worst thing of all is having no hope for the future. Where there IS hope, you need to cling to that hope and keep working toward it.
I can't say I ever felt the "not a real girl" thing but honestly before transition I didn't know WTF I was but I knew what I wasn't. After transition I found out what I was, just a girl like all the others - not a lick of difference. It never occurred to me that there could be anything except female/woman and male/man.
The 35 years since transition hasn't been all sunshine and roses. There were tough times. My life took quite a different turn from what I had dreamed it would be, but it's okay - I was fully ME and I could handle it.
I never once doubted who I was (a normal woman) until I came to the forums a few years ago. I was a woman, the world knew me as a woman, and nobody thought anything about it. It is only in places like this where people debate "what is a REAL woman". You are and you will be what you believe yourself to be and what you allow yourself to be and nobody can define you except YOU.
When I am blue, I go out and buy something I REALLY want but can't possibly justify or I go to the salon and get 'the works'. Fortunately that doesn't happen too often or I could never afford to retire! LOL!
