Decided to cut out alcohol

Lately, there has been so much stress going on in my life, from finances, family, and just overall mental stress that I have always had, plus trauma from my past. I used to drink almost every day, was sober for a year, and then went back to drinking. Which slowly turned into every weekend, and some weeknights. I thought since I wasn't drinking every day, I was okay. But between my husband and me, we'd drink an entire 750ml in a night. We would have so much fun. But the past month or two, I have had two really bad nights, and it is from not knowing my limits, especially when I mix alcohol, I have noticed. Ex: blackouts, not full, but only remembering bits and pieces, saying mean things to the person that I love most in this world, that I have never even thought while sober, crying, and making that person look bad in ways I did not mean to. And I am just ashamed and embarrassed of myself and how the loml and his family have seen me get. So after the last bad weekend (this past weekend), I have decided to seriously cut it out for myself completely, and for my husband. The only thing is, one major thing I have always used alcohol for is that I am so socially awkward, and it feels like I can't be my full self unless I am intoxicated (singing, dancing, being goofy, etc). But I just keep tending to push it past the fun me limit, and I turn into something I hate hearing about/thinking about the next day. I was just wondering if anyone has some advice on coping with things like that. And how to finally be comfortable with yourself without needing alcohol as a solution. I am just worried that without it, I will become boring, and just keep overthinking relationships to the max. I am also worried that they will not get over the things that I have done, and never forgive me / always see me differently. Any advice on anything I mentioned would be very much appreciated. Just really need thoughts from people who have been through it. Everyone around me is a drinker and does not plan on being sober.
