It is a while off, who knows what will happen. But there are lots of threads on here re handling social events, e.g. Advice for holidays, parties, weddings, etc
If it is social family gatherings, then go early, leave early. Spend time with the kids, have fun and be silly. Be the designated driver. Or drop the family off and make your excuses if you can’t trust yourself.
Try not to get too hung up on it, see how you feel at the time.
