I can relate to the self-loathing, remorse, and feelings of humiliations. You are not alone in that department.
The only way I found to get rid of those emotions, is to stop drinking, forgive myself, and work on my sobriety among some other things.
As for meeting new people, there are plenty of other ways to meet people besides being a barfly. AA is a great fellowship, you can join a grassroot organization, join a club (***** has groups for everyone), or take on a new and sober activity.
However, first thing is first. You should probably put the plug in the jug since it sounds like it is destroying your life and yourself. Then get some help. Hang out here and maybe attend an AA meeting or SMART Recovery.
