Dear Huffer
Welcome here

I think you've taken the right first steps, congratulations

Having a diagnosis is the first step towards recovery, so persevere on and you'll eventually recover

IMHO, your best friend's reaction is the LAST thing you should be worried about, since she's still speaking to your wife.

For now, your recovery is FIRST. In fact, you could use this (your relationship with your best friend - her not talking to you) as an issue that you could work on and explore in your recovery process - ESPECIALLY examine your abandonment thoughts / feelings and the dynamics behind it.
I did this (my mentor's silence was bothering me), I used her silence and ignorance of me to deeply explore my own abandonment fears and so on. And it has helped me a great deal. (

And I think you have a great wife, so be extra extra thankful for it
Hang around, read others' posting and glean some insights for yourself, as well as learn to apply the tools here.
We can all recover! hehe
