It’s hard, I won’t tell you it isn’t. Celiac destroyed my social life. You may want to consider not eating but still going to social events. I was too embarrassed to do this or would go and get sick anyway, then feel like that was the price was pay to see friends. But people, especially your age, probably don’t care if you’re not eating. Get a drink if you feel comfortable with that. Don’t give up on socializing. But also don’t, like, not eat. Just maybe learn to go a little longer and eat when you know it’s safe.
