I am the link

I hold the ones together that are exploding apart

For them, I am the only thing that keeps them from breaking

I bring people together 

For them, I organize ones who would otherwise not gather in one place, in one time, in the present 

Nothing happens when I am gone

Or nothing that this part of the chain knows about

Everyday people use me

They cling on, depending on me to bring them closer, to have new experiences 

The weight is heavy, but the link tries to stay strong 

But how much weight can this one link hold until it breaks?

I am the link

How much more can I take?
