Any tips?

Hi guys my surgery is in a month bang right after my exams

Double whammy…

And I’m just wondering what are the best things to do? My mother is definitely over prepped we have like chin straps, humidifier, IV water things? (Idk the name tbh)throat spray, basically everything to help the pain, but what else can I do, I’m very very anxious and I gotta be honest I think I’m stressing more for my tonsillectomy than my exams
