I would recommend reading "The Easy Way to Stop Drinking." I hate the title of this book (hello, "stopping drinking" is NOT easy), but the book itself is great and puts a positive spin on sobriety.
It sounds like you might just need a new outlook on sobreity - this book did it for me. I previously thought the exact same thing: not drinking sucks, I'm losing friends now, etc. Reading this book helped change my mindset.
