Hi there, I can definitely relate. I hear music on the radio that I used to dance to while I was out partying, and I get nostalgic. It does help to play the thought of drinking through, to see that it might be "fun" for a couple hours but it can lead to dangerous decisions you regret, and overall anxiety and depression.
I second the advice to find sober/recovery people as a support system. My sponsor and her sober friends like to go out dancing all night sober, and she is going to invite me next time.
The party doesn't have to stop just because you stopped drinking. But it's helpful to find friends and environments that support your desire to stay stopped.
Best wishes, keep going strong.
