Hi Ellima,
I know what its like to miss your best friend...lost mine too when xabf and I split. I miss the banter, funny conversations, playing sports together, long talks...of course, when sober. I have tons of other "friends" but none that could take his place. However, when the loneliness gets to me, my dog, Pasha, is there to love me back to happy thoughts!
Sorry for your pain...
Peace
