Exhaustion and Chest Pain after Purging

Hello! For background, I’ve had purging disorder/bulimia for roughly 6 years now and it’s become relatively routine for me to purge multiple times a day. Last semester, I had a communal bathroom so I would only purge generally 3x-4x a week after drinking or the occasional binge. However, now that I’m back home for break, I’ve returned to purging multiple times a day.

What’s concerning to me is after purging, no matter how easy it is, I get extremely fatigued and my chest hurts to the point that I have to go get something to eat. I know nobody here is a doctor, but is this relatively normal? Should I be extremely concerned? I’ve gotten fatigued after more intense purges before, but nothing to this degree and never had chest pain as bad as it’s been recently. If anyone has any insight whatsoever I’d be extremely grateful!
