I think the other thing you have to remember is that physical changes take years. There are charts that give outlines for each thing that will change on HRT, however I'm just finding recently that when it comes to things like breasts, while I did have growth in the first 6 months to a year, their growth did seem to stop, however now that I'm at the 3.5 year mark (and I haven't had a BA), they seem to be growing again. So some changes will take longer than advertised and you are basically going through your adolescence again where you might've had a growth spurt when you were 8 but then nothing really happened until you were 12 when you went through another growth spurt.
So you will pass. And we all have insecurities because we are transitioning.
