In typography, the mean line, also called the midline, is half the distance from the baseline to the cap height. This may or may not be the x-height, depending on the design of the lower case letters. A very high or very low x-height may mean that the midline is above or below the x-height.
This confusion has been perpetuated by books, and web sites, on typography which copied from books on type back to the original book or source on type that first failed to clarify this difference.
Round glyphs will break (overshoot) the mean line slightly in many typefaces, since this is aesthetically more pleasing; a rounded shape will appear visually smaller than flat-topped (or bottomed) shapes of equal height, due to an optical illusion.
i need help i cant leave i cant breathe. i see my way out but
I'm in too deep to care. emotionless, i feel myself about to break.
self-destruction, self corruption, this life i know, this life i hate.
with each passing day my outlets slip away. i believe the lies and
i dig myself in deeper. i play a daily game of tug a war between

passing blindly by my chances knowing some day i might die. in the
silence of my nightmare noone else can hear me scream, noone else knows
what i need, noone else believes, i could die and not care. i need
something to set me free. reflections from my past that seem so unreal
to me, I'm out of touch i can no longer feel me, my heart is sick and
my mind is reeling. don't know myself, don't know why i still don't care
. I'm the only one that's paying, and I'm the only one that's playing.
the more i struggle the more i lose. i dig myself in deeper and still
don't care then the moment comes when you reach for my heart, i know
