Am I Invisible?

Recently, I feel I'm invisible among my friends, even my besties... Why?
Seriously I hate myself being a tool or some other useful stuff for my friend, or an extra person to share some cost, or a human navigation system to lead you everywhere, or myself as a final option for hangouts...
My sincerity, is that so worthless?

This song writes out everything from my heart...

Invisible - Skylar Grey

[Verse 1]
I take these pills to make me thin
I dye my hair, and cut my skin
I try everything, to make them see me
But all they see, is someone that's not me

[Chorus]
Even when I'm walking on a wire
Even when I set myself on fire
Why do I always feel invisible, invisible
Everyday I try to look my best
Even though inside I'm such a mess
Why do I always feel invisible, invisible

[Verse 2]
Here inside, my quiet hell
You cannot hear, my cries for help
I try everything, to make them see me
But every one, sees what I can't be

[Chorus]
Even when I'm walking on a wire
Even when I set myself on fire
Why do I always feel invisible, invisible
Everyday I try to look my best
Even though inside I'm such a mess
Why do I always feel invisible, invisible

[Bridge]
Sometimes when I'm alone
I pretend that I'm a queen
It's almost believable

[Chorus]
Even when I'm walking on a wire
Even when I set myself on fire
Why do I always feel invisible, invisible
Everyday I try to look my best
Even though inside I'm such a mess
Why do I always feel invisible, invisible
