To some extent I was the same way. Drinking a lot combined with ending up with women to alleviate the feeling of being alone. Sure, I may feel wanted and needed one night and it feels great in the moment but, as a result of all the "fun", I could feel used for money or taken advantaged of in some way or even be exposed to some incurable STD.
Loneliness is a very difficult feeling to cope with without alcohol but what really helped me is going to all kinds of meetings available out there (i.e. AA and SMART Recovery) and staying busy doing things I enjoyed doing that didn't include booze. Eventually, along your journey you'll come across someone who is experiencing the very same thing you are and, like me, something will click and you'll realize you're not alone in this. We are not alone.
Best wishes.
