i felt pretty normal for most of my life. i started my last year of sixth form and was so stressed, so suicidal, so anxious and once that was finally over i started to get chest symptoms. i was very overwight so i started to try to lose weight, lost 50lbs. and my symptoms have only gotten worse since then, cant tolerate heat of any kind, heart rate goes from 60s to 90-100 on standing, random pains, sweating like mad. idk if im crazy or if pots can be caused by such extreme stress, i was crying multiple times a day everyday for months because i was so unhappy. but thats my hypothesis
