You say that you have friends now, but if you stop drinking that you won't. Are these really your friends or are they just drinking buddies? If this is the situation, then real friends won't care if you stop drinking.
If you have a desire to stop drinking, then try an AA meeting. Reach out and tell people this. I have made many wonderful friends in AA who I would have never expected to meet. I would advise putting the plug in the jug, trying an AA meeting, and reaching out.
Perhaps you have been drinking a lot and don't know how to make friends sober. This was certainly my case. It took time and effort on my part. True friendship needs the time to grow.
You could also join a club or a grassroots organization. I have met some wonderful people that way too. There is group for everyone on ***** Groups.
