lets talk about what were the sequence of events that led to your feelings of anxiety.
for me, i was in Germany at the time. my right gum was swollen due to a previously repaired tooth that cracked. i went ahead and pulled out the piece myself and panicked during the whole process (with all the blood and stuff). the next few days i started developing some tightness on my temple and my vision started to get weird. subsequently stayed in the hotel in the afternoon in fear and kept researching my symptoms
prior to that i talked to a girl i recently broke up with. i felt useless as i couldn't help her depression.
