How are you?

I am at a lost for the right words to express that to you.
Of course, the typical and most siught out answer is I am fine.
But that my friend is not always the case.
You can easily answer tired, good, busy, worried, upset, happy, stressed, and many other things.
Of course with all those answers there is another question implied? The why and how come you feel that way?
Then there is the rare case of a few, including myself saying that I don’t know how I feel or you feel like an odd mixture of them all.

To tell the truth I am not sure as to why I wanted to write this but maybe it is because I myself wanted to know the reason behind what I am feeling?

Right now I am preoccupied, extremely tired, and somewhat content. How do I get that mix?
No clue but as of right now I will stop for the moment.
