I completely understand how you feel.
I'm lucky that I was born with a good amount of T already. So I'm hoping my dosage won't have to be too much. I mean, I've already got the muscle on my arms, veins in my hands and a strong jaw, it's just really the arse that I want to firm up [and the obvious things changed]. XD
I think that once you finally come to terms and start knowing where you are in life, your confidence really picks up. Of course, it always helps to have some support on your side, too.
