Yeah its funny how were going through the same thing. Except for the anxiety part. Im also 20 and I also have alopecia. I had some patches on my legs a while back. They injected stuff on my hairline but it didn't really do anything. I'm not too sure if my hairline is receding because of that or if i have early MPB. Im going to shave my head regardless soon though so it doesn't matter

. You actually look pretty cool with a shave head lol, shave it lower and get fit thats what I'm doing. If you want to keep fighting for it go for it maybe you'll get you hairline back who knows. But honestly Life's to short to be worrying about your hairline all the time.
