Just some words. feedback would be cool.

Hiding how you feel
Behind a shield of vicious wit,
Criticising for the sake of criticising,
When you really don’t give a ****.

Using jokes and sarcasm
To cover up your fears.
Peals of hollow laughter, ringing in your ears.

And what good has it done you?
People like you? Sure.
You’re amusing? Good.
But was that all you were aiming for?

Are you so ashamed
That you feel as well?
You’re a ****ing human being,
Jump down from your pedestal.

You’re all so bloody fake,
Pretending everything’s ok,
Too scared to be called attention-seeking,
Too scared just to say:

I need you.

One day you’ll stop hiding,
You’ll admit that you need more,
You may not gain understanding,
But perhaps you’ll feel less unsure.

One day you’ll stop pretending
That you’re somehow better than me,
Just because you mask your hurt
In a layer of stupidity.

How do people buy it?
The empty jokes you crack.
Too absorbed in their own lives,
To see you’re about to snap.

One day you’ll stop hiding,
You’ll admit that you need more,
You may not gain understanding,
But perhaps you’ll feel less unsure.

Nice, it's got good flow and the first verse (a solid opener) really cracks on the last line. In the 3rd line I might just say "Criticizing for the sake it" but maybe that's just personal preference me.

Not "just some words", I think it's really good

Meaningful words!

Same here: I'd change the same part in "Criticising for the sake of criticising" into of doing it or simpler of it;

But otherwise it's a very good one!
