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