ugh you again. why are you testing your T levels at 18?
I believe I already explained to you as a teenager not everyone your age peaks in their late teens and not everyone is done developing. your hormones CHANGE as a teenager, they don't necessarily peak. there is a major difference
this is likely all in your head or you spent too much time playing video games and watching tv. gotta get your hormones stirred up.. go workout, go play sports, get outside
