First, remember that a strict whole30 is just 30 days plus your reintroductions, it's not forever and isn't intended to be. Those occasions with friends are where your food freedom will come into play, once your whole30 is over -- then you get to decide if a glass of wine is worth it, or if you'd rather stick to something non-alcoholic, and you get to decide if it's worth it to you to sometimes have non-whole30 foods while you hang out with friends. Sometimes it might be, sometimes it might not, but it will be completely your choice, not some rule that someone else has set for you. Sometimes it is easier when you know you can have these things if you want them, but you decide that you don't.
It may help to find things to do that aren't centered around food. For instance, you could go to museums or shows. For me, I met most of my close friends taking craft classes and we still go take classes or hang out and craft. Or you could hike together or enter fun runs or 5ks. Go learn rock climbing or take dance lessons or archery lessons or axe throwing.
If you do tend to get together for meals or snacks, find places that have foods you can eat, or invite them to your place for a meal or a movie or a game night. If you tend to always go to the same one or two places, see if you can talk to the chef or someone in charge (at a time when they aren't busy), and see if there's something they could come up with for you that would work so there would be something you can order when you do want to have something to eat.
