Welcome, Kitty!
If your social life revolved around drinking (even though you did your problem drinking in private), you might need to readjust your social life for a bit. Hanging out in drinking establishments is a VERY bad idea in early sobriety.
It certainly doesn't mean the death of your social life, though. Once you are on solid ground you will have no need to hide from alcohol--if you are on solid spiritual ground you can go anywhere you want and do anything except drink.
Don't expect your friends to understand right away, if ever. They don't have to understand. YOU know what your drinking did to you, and that's all you need to know. Some of your friendships may change, but concentrate on your recovery for right now and it will all fall into place in good time.
