Writers' Bloc

It is very frustrating when for hours you stare at your computer screen with the 'new post' window open and nothing in your head pouring in.

For over a month I have been going through this dilemma; typing out words and then deleting it. What may be the reason?

Have my thoughts exhausted?

or

Too many thoughts, but no structure to it?

Am I not observing things?

or

Observing too many things, to reflect on?

Am I not spending much time with myself?

or

Spending too much time, to give myself a thought?

I don't know how long would this phase haunt me and I lose all the words to design my wanderings.

Afterall, Writers' Bloc is every writer's fear.
