Different Ink

I have a jar where I am saving up for a tattoo.
The funny this is, I already have a few.
They aren't the kind you normally see,
because in this case, the artist was me.

I didn't use ink like most people do.
No, this was different. Not a real tattoo.
It says words like screw up, ugly, and fat.
Reminding me I'm even more worthless than that.

Could they invent a mirror to show what others see?
Would I even dare look? What would there be?
They tell me they love me. They tell me they care.
I say that they're lying. All they do is stare.

I'm stuck in my own skin. Help! How do I get out?
A fish out of water, I'm just flopping about.
I don't belong here. I never did. Sometimes I think, I'd be better off dead.
