touching it, and then...

It is heartbreaking to see someone you care for- when they have this cloud of gloom in their eyes. You feel its because of you, but then you don't know what to do- You leave them, thinking they would be happier if you were not around, but then you know deep down that would make it worse. So, you just touch them, till they stabilize, till you have the strength to, and then you exhaust and crumble. Now maybe you have nothing more to give, and they don't need it either- Even worse?
