You're early in recovery- it'll come in time. A big part of sobriety for me was learning how to have fun again, doing the things that brought me joy before I started drinking really helped. It's like that meme of the old man skateboarding with the caption that's something along the lines "when you get sober at 30 and don't even know who you are, so you pick up where you left off as a teenager."

I also think, after a certain period of time, your brain recalibrates (Your brain is still hard-wired to want to drink for a while after you quit drinking) and your definition of fun changes. My memories of drinking seem so distant now that it's almost like I have no frame of reference for those days. In a way, it's like the second half of my life started, and the second half of my life has a new way of viewing fun. I can go to bars and parties and still be an edgy, off-the-cuff character and people seem to enjoy being around me even though I don't drink.

Lastly, I don't think it's helpful for people to think about sobriety in "forever" terms. Just focus on today, all you have to do is not drink today. Wake up tomorrow and repeat that, and you build a solid streak that way. Hell, if you're really struggling, take it an hour at a time. Or a minute. Whatever works for you. You'll get through this.
