Ah Macha, how you sound like me.
As far as saying your grand when your not, I used to do that until I found a therapist that specialises in gender issues. I remember 5 years ago I took too much ecstacy, tipped myself into an episode of extreme depression and dissacociation. Worst episode of my life.
My point is, I had to see a psychiatrist then just to get my head back in shape. After a few months, I thought I should ask him about gender dysphoria, as That was the main thing on my mine. The reaction I got was mainly dismissive, Acknowledging me, but in a way that he was doing his job without ruining his reputation. My point really is, he was a mental health professional that was ready to dismiss my feelings in a heartbeat. My current person, who I have only seen once, is amazing.
The internet is your best friend really. imo.
