Awwwww I am so sorry. I know nothing can compare to your friend who is gone.. But maybe.. You need.. A puppy! Lol.
I just got a puppy and he makes me very happy.
I have to admit though, it took me five years from the time my last dog ran away to get this puppy. Should of done it sooner.. But this puppy was meant to be..

Anyways I'm sorry and you can pm me if you need someone to talk to!
