I am trying to write but i can't.

I'm trying to think
and I feel like I'm on the brink
of something.

I'm searching through my mind
trying to find the words to say,
struggling every single day.

Like a dam,
the river of my thought has been blocked,
not locked but left closed,
because I lack the strength of those
who can hold it open,

I think I've lost touch with the heart of my imagination,
and so begins my creative degeneration
