Antiaris is absolutely correct. Whereas I have never physically purged, when I had that "cardiac event" (the heart-attack precursor) it began as a tight gripping pain in my chest. It's effectively when your body has exhausted breaking down your other muscles and starts to seek nutrients by breaking down the heart muscle.
Terrifying thought, right? But enduring the ED you switch your mind off and go, "Nah, I can get through this no bother." - continue down the same route, keep restricting, then BAM. Have a minor heart attack. At 26 years old. As I did. Terrifying.
I am perhaps going to make a hypocritical statement right now however; I have had a very difficult last few days. I will share this with you regardless.
This is the time of year that, within a two-week period, five close family members (myself included) have our birthdays and as such, parties are inevitable. However on my recovery I have found I am eating 2200 kcal on my meal plans, and over the past week or so have maintained at 96.6lb. This morning, I was 2lb heavier for absolutely no reason. It made me worry that the weight gain was "saving up" to sneak-attack me and freak me out. I have eaten no more or less than I have for the past week but this sneak-attack weight gain scared me a lot.
And with the birthday party stuff coming up, all I am now thinking is "just think - if you can get blindsided by that pound and a half overnight, think of how much it'll nail you after two weeks of birthday celebrations!"
Needless to say, despite fluoxetene/olanzapine, my anxieties are ear-brain-seeptastic.
