I NEED HELP WRITING MY BESTFRIEND WHO'S IN A COMA A LOVELY LETTER :( HELP.?

alright.. so what happened was my best guy friend got in a coma. he was snowboarding and tried to do some jump but landed funny and fell right on his head (and no he wasn't wearing a helmet). they found him on unconscious and he was airlifted to a hospital. he's been in a coma ever since this last saturday and i feel so terrible. he cant talk but he can apparently hear so his close friends are writing him letters. he's such a sweet guy and he's one of my best guy friends! i miss him so much & i pray for him everyday hoping he'll get better. he's a strong guy and i know he'll get through all of this. my prayers go out to him. he's the bestest friend i could ever ask for! and so i wanted to write im a paragraph. just like a letter about our friendship and how i want him to feel better but not gonna lie i kind of suck at writing and stuff, so i came here to ask for help to write this letter. anyone have any idea's? if so please comment and let me know what i should say :) please and thank you!
