How can I deal with unsupportive friends when going sober?

Have had an active drinking problem for about a year or so. Have decided to go sober and have been sober for two weeks so far. It’s been really hard but worth it.
A friend that used to call me her “bestie” has shown me no support at all. Hasn’t reached out or even brang it up in conversation when I saw her at work. I have also tagged her in a few things on social media and she didn’t reply.
I knew I would loose a few friends but not someone I thought I could lean on for support.
