There is nothing you can do. I am sorry. Friends usually split down the middle. I too lost a lot of friends and it hurt like crazy. Last week I had to set next to my WW best friend at at work event. I know the "best friend" believes I am the devil incarnate but there was nothing I could do. I just tried to maintain dignity and just said hello.
Hang in there and the truth will reveal itself. It always does. Remember the quote from MLK - the arc of the moral universe bends towards justice. I hope that brings you some comfort.
