How do you politely explain to people that while you want to see them very badly, the thought of having face to face interactions is so stomach churning, anxiety inducing, and world ending that you can’t even begin to imagine the next time you can hang out with anyone?? Like??? Sorry I can’t make plans I hate myself and everything else???????????? I’m doing you a favor????
Why don't you tell them to surprise you... and go on from there...?
