My self-proclaimed therapist response is, get new friends and your life will blossom again. No need to rush out and go looking, as "birds of a feather flock together".
My advice is... have the confidence to know, your social life will return, but you have bigger fish to fry at the moment with your health and your overall emotional well-being. Sounds like you need more YOU time, more than bar time anyway. Especially with people who seem not to care about you, as they do their drinks anyway.

I can appreciate you feeling isolated, but consider it a blessing and opportunity to work on yourself. Everyone enjoys being around a well adjusted dynamic adult, who knows them self and can feel confident in their own skin. Sounds like you are making changes like every butterfly does. So I wouldn't expect to make big changes by becoming healtheir and stronger, and still expect nothing else in your life to change as well. (Including "friends", nothing you stated would make a difference to a real friend who wanted you to be happy and healthy. I think you have drinking buddies, not friends.)

Also I am an addict, whenever I take one addiction away, the addictive personality in me searches to place that addiciton elsewhere. so, I think it is very wise to stay clear of bars for the next couple years, so you don't have that issue on top of what you are dealing with today. There is a saying I learned from my first procedure, "as the weight comes off, the issues come out." No one who needs weight loss surgery is free from lot's of issues buried under their fat. Including myself.
So just think about that as you continue the roller coaster you are on, as you are a strong person who wants to improve your life, thus you made the difficult decision to go down this path. So stay strong and stay the course, drink and walk, drink and walk, and write, write and write about your emotions and food.
I hope this helps, forgive me if I am off base.
