Human.

At one point I'm invisible

and the next there are too many lights

I'm suffocated by too many people around

but yet I am alone

I am wounded as I am badly hurt

but no one can heal me

Scarred are my hands

but so quick are they to embrace him

There may not be demons in my head

but there are demons in my bed

It scares me to trust

but yet I feel I do it too much

What am I?

Human.
