How To Retrieve A Lost Draft From A Fb Post You Were Writing?

Hi there.
I was writing a post using chrome on an android smart phone on my Facebook page and it was just going to be a few sentences about what I thought was the meaning of life and as you can imagine it turned into much more than a few sentences. In fact it was a outpouring of the deepest thoughts in my mind a discovery of my own truth I was excited not so much about sharing my thoughts but about what I was discovering about myself. Anyway I got near the end and I was going over it to correct mistakes etc and to see more words at once instead of just the small window I ended up fingering it into oblivion. I would really like to find it because it was a written document of my deepest self a picture and perspective of something that only comes to light when it is written down.

Next time I will use a pen and paper
