Hang in there. I know where you're coming from, being stuck in that stage where the problem is your face and no amount of haircuts or men's clothes or aggressively standing with your legs wide apart and waving your man-flag around would change it. I know people are only trying to be helpful and make sure you've got your bases covered when they offer tips about how to dress and how to move and all that, but honestly sometimes the only thing you really need is the hardest thing of all in this situation: patience. Which I'm not much help for, as I don't have any, myself. All I can say is that it did slowly start getting better for me around the time I was approaching the one year mark. Now that it's been a little over a year, I pass more often than not but still have people who knew me from "before" going on as though they haven't noticed any changes. And the minute someone who doesn't know you gets that confirmation from someone else that you're a "she", game over. That's how it is for me, anyway, ymmv but yeah this is a really uncomfortable spot to be in.
Everyone is different, genetics, blah blah blah, but if you're concerned that you're not where you should be, there's no harm in discussing it with your doctor even if the charts say your T levels are normal. There could be other factors at play that need ruling out, or it could just continue to be a waiting game. Considering that there are plenty of cis men who also don't pass, though, I'd say your best bet in the meantime is to get comfortable with correcting people. That's something I struggle with, but I've been lucky enough lately that the ugly prepubescent facial hair usually tips the balance in my favor. If you can't grow a beard, you gotta grow confidence in your gender. Both is good, but we can't all be so lucky. At least one of the two will usually help.
