I didn't know your friend in person, but I'm sure he was a very nice guy and that you guys had a lot of fun together.
I'm sure he saw you as a great friend too.
Anyways, whenever you feel the need: You can always talk to me. I'll be there to listen, give you advice when you need it, to laugh with you and to show you that I care.
You are a great person and I'm sure your friend thought so as well. I'm sure that he'd want you to be happy and enjoy the rest of your life, even if he can't be with you anymore.
Always remember that you are loved. (:
