Is it safe to swallow air and can anxiety make you burp they ran out of co2 for my wip cream and i saw aid bubbles in my drink anxious?

Yes, I think so.: The amount you drank is quite small and even larger amounts would probably do no more harm than a need to burp - babies do that all the time. It might even be a bit uncomfortable till you burp, but not dangerous. Relax if you can. Relax if you find it hard - try! you will be fine - but do find a good therapist to help with the anxiety so you'll feel better in the future. Best wishes!
