I know I was very uncomfortable with being happy. I didn't trust that emotion and I sabotaged things more than once to scurry back to emotions I was familiar with.
But...drinking ceased to become a viable option, so I had to get used to feeling peaceful, happy content and securely sober (just as I had to deal with soberly feeling scared lonely angry etc)
It's a process. We grow into it
Have patience - and faith - and I reckon you'll be ok shortstop
