L1 "in my head" doesn't sound like a great start to me.
There are a lot of creative ways to suggest that the letter was written in your mind without coming right out and saying it.
Your footnote has been taken into consideration so I will just say that with some removal of extra words, consistent punctuation and line breaks, this will greatly improve. Kinda nice tho.
I'll revisit this after a while.
whattya think now?
the spacing seems a little off to me, i might play around with it.
other than that, im pleased with the content, but im not sure about the flow?
suggestions are really welcome.
