Linkin Park - Crawling Lyrics Meaning

In my opinion... it's about panick attack @ anxiety disorder..

" Fear is how I fall "
Fear is the most common way to distract the anxiety simptom..

Perhaps songs giving us how to resolved the problems...

" This lack of self-control I fear is never ending "
Controlling....
Self control.. how to relax and calm during the attack.. it's about mind control..

" I'm convinced that there's just too much pressure to take "
When to much pressure the harmful stress will bring to anxiety..

" I've felt this way before
So insecure "
Not "insecure" but it is "in secure"..
Anxiety disorder have always prepare with self remind.. when panic attack setback happen..have to believe ownself that it was not a first time happen and it always safe.. no fear..
