I cant eat at at school lunch because i get nauseous. Im going there for like 3 weeks now and its not getting better, shouldnt anxiety get better when im exposed to it? i got this anxiety after quarantine. 
i also noticed that im nauseous only when i think about nausea (works only in highly uncomfortable places, at home i cant get nauseous from anything)

Im having beakfast, i meditate, i use ginger candy(it should help with nausea, but really it doesnt do shit), i drink enough water, and im in pretty good shape. 
Idk if this helps but im still teen. 

ik i have some problems eith social anxiety, conciously i dont care what others think but when im not thinking my subconsious mind always wants to please people, and cares what others think of me
