The best bit of advice i can give is, it's a journey, and it's a hard one. You need to have the strength to do it, our lives aren't for the faint of heart. You need to find little wins where you can to keep your spirits up. I guess i'm lucky because i've only had one episode of crippling depression in the last 9 months, that was when it seemed like there was no hope of me getting my top surgery. I spent a week laying in bed in the dark, not talking to anyone, crying and looking up steps on how to go about suicide. It was bad. But I got through it. By the eighth day I began researching harder, I found surgeons all over Canada and the next day I started calling them, and I found a surgeon who could take me before I went back to school. Now I feel happy again.
I still don't pass very well, my voice still hasn't dropped, I don't have the facial hair I want, I had a lot of my eggs in a basket waiting on the tyron 3 but it was a complete bust, now I don't know what I'm going to do with regards to my junk, but that's ok. If my voice continues not to drop I'll begin taking voice therapy to lower it, if my facial hair doesn't grow in where I want it to I'll deal, I'll deal with my junk when I am independent and have more personal funds, maybe surgery will have improved enough for me to personally justify spending the money. Maybe it won't.
They can actually create functioning organs from completely dead tissue now. It's still a new practice, but whose to say that in 10 years time they may not be able to actually create a 100% functioning penis for us transmen?
Find things that are going to make you happy, look at what's making you unhappy and change it. Look at your main depression, and then figure out what all the little things are that's setting you off and begin to address them one at a time. Why do you feel that having bottom surgery won't make you feel better? Do you not like the current way the surgery is done or the current outcomes? Then maybe wait a few years and see where Tissue Engineering has gotten too.
All in all, it will get better but only if you work hard at making it better.
