well you certainly threw me for a loop at the end! i liked this short letter :] it conveyed so many emotions.

Geeze! Not only do you know how to make your readers laugh, you can make them cry just as hard! This was absolutely, brilliantly heart-wrenching! And I loved the twist at the end. I thought, when I started this, that it was about a breakup, AND THEN SHE DIED?! What a way to tug on the heartstrings!
I thoroughly enjoyed reading this!

Overall it is very good but sadly I cannot keep up with your genius Alex. The ending confused me a little as I couldn't understand whether she was literally or metaphorically dead. Other than that it was a sweet and tender love letter and you feel really into your character.
Now this isn't a critism of your work but I thought I should say that though good, there was nothing striking or unusual about it.To stand out from the crowd you have to be original or possess the "X" Factor.
Still I loved it and am looking firward to reading more.

I like it, I think I understand the ending. Presuming you want criticism...

The start: Pehrpas with this being a letter the second I miss you isnt needed as it isnt how it would be written.

Also you say 'but I gave it a damn good shot' I dont think damn is in keeping with the language used in the rest of the text, it spoils it for me.

Theres also a little bit of proof reading and checks to be done but other then that. Well done.
