Sorry I'm late seeing this, @Anastasia 😞 And that your anxiety was so bad yesterday 😞 I really hope the covering two roles doesn't continue - that some other solution is found. Would your boss be understanding if you explained that it was too much? I'm sure that's better than you being off with sick leave for anxiety or burnout, while there's already a staff member away...
I think you're amazing, visiting your friend while feeling so overwhelmed yourself. I hope the visit went well and that maybe you were able to get some support yourself, from your friend.
Yes, I'm doing OK, thanks 
Sending you a biiiiig hug...how is your anxiety today? 💙
