I know how you feel. I've spent many days locked away during detox. No sleep, barely able to eat/drink without vomiting, anxiety through the roof etc. It takes me 3 days to completely feel normal after a bender usually. My trick is usually to binge watch a TV show on HBO or Netflix until I am able to go out in public again.
Don't think about summer BBQ's now. Just get yourself sober and healthy first
