Welcome to Susan's Leah,
I'm so glad that you've found us. The big thing to remember is that you are amongst friends here, so you can relax and enjoy what this site has to offer. You will find a wide variety of people here with a wide variety of views, and opinions, but don't let that scare you off. Just be sure to add your own.
I can personally relate to those dark periods of your life that you have described. And I'm sure that there are others here who have experienced them as well. I can remember those times when I took things into my own hands a tried to correct an obvious biological error, but that was many years ago now.
All I'll say at this point is that there is always hope. I'm 53, married 33 years, have a grown daughter, and while my transition is a late one I have the benefit of having experienced much in life and it's complications.
I have the rest of my life and so do you. Yeah those hoops are a lot harder to jump through at our age, but while the young have fitness and agility, we have cunning and guile.

Again welcome to Susan's, I'm sure that we'll chat later.
Steph
