When is it Enough?

Life continues to pull and pull and pull at me, Never letting go, Until I nearly fall apart. When is it enough to break me? Everything I do is taken for granted, Everything I say is left unheard, And everything I accomplish is diminished. When is it enough to discourage me? I do my best to please everyone. I volunteer to do things when I already have no time for myself. I drown in oceans so that others may be spared from the tide pools. When is it enough to drag me under? I just want to be enough. I just want to say enough. I just want to have done enough. When is it enough? When am I enough?
