(23M) People who struggled without alcohol, what helped you?

TL;DR : My anxiety and overthinking consumes me when I'm sober. I've noticed how I rely on alcohol for a social life and, especially, a love life.

My issue is my anxiety is overwhelming most of the time (there's a whole underlying issue behind that, I can elaborate if requested). I never flirt or hit on girls when I'm sober because the anxiety consumes me and I usually walk around with a resting b*tch face because its easier than faking a smile and masks the anxiety. It also often let's people know I'm not interested in chatting when they hit on me or try to talk to me because its easier to get out of the interaction and the panic. 

When I'm intoxicated its like I'm a casanova. I get with extremely attractive women, and it feels great. But I've noticed I'm ONLY doing it drunk. Thinking about it now, I've barely ever kissed a woman sober... 

Im away in another country and I got asked on a date by an absolute worldie of a woman. I went sober as she wasn't drinking. My heart was literally pounding out my chest. My hands were shaking like crazy, as if I had parkinsons. I was struggling to talk properly (stuttering and all, but she found it cute), my chat wasn't great and I could barely hold eye contact until maybe like an hour in, when I felt more comfortable. She noticed the shaking when she checked out my watch and literally just held my hand and arm. Overall it went extremely well and she's asked me to meet her twice since, and its been 2 days since.

This made me realise how much I've been relying on liquid courage etc. But I'm sick of it. I'm just using it to numb my anxiety, sometimes to the point where I'm that drunk guy. My chat becomes great when I'm intoxicated because my anxiety is suppressed, so I'd love to see how good it could be if my anxiety is alleviated when I'm sober and my brain's running at sober pace. But I literally feel like a different person after 2 drinks to when I'm sober, not even when I'm drunk.

Has anyone been in a similar position and managed to overcome it? I have alcoholics in my family, and I'd hate to go down that route or be someone who's reliant on alcohol for fun.
