At A Loss Of Words

Writers block can be your biggest downfall.
Sometimes writing is the only way to begin things, end things, confirm things, discover things, the list goes on.
So why is it that, when what you need most is your words and emotions in a complete sentence, your brain comes to a complete stand-still?
Right now, I can't think of anything to describe this, all the questions i have, all the anger, the embarrassement, the "how could i be so blind?".
So how can i possibly successfuly learn what i want to know, and what im told i should know, when my brain can't possibly form a sentence that makes sense

or even the right word for that matter.

forget about it

My belief is that what happens in the past should stay in the past.
there is no point in living in the past because life is so limited.
why waste the limited time that we DO have staying concerned about what could have happened, when in reality we could actually be limiting the time that we have by doing so.
im gonna stick to that belief as much as it may seem unreasonable at times.
Im not saying hide your feeling about the past, im saying forget about them.
