Why don't I have "normal" signs of an ED?

[whyisjordanskinny]

Mine is 18.2 and I lost mine. But, I went from 135 lbs to 103 in like three months.

I lost mine in the healthy days, i was slender but naturally so and ate plenty and yet i lost them shortly after i got them actually, i assumed they would come back, just sort themselves out but they didnt and now they have no hope. Guess your just lucky, you can have the kids while i probably will end up in a house of cats. I should have gone to the docs forever ago but the longer ago it gets the more certain i am that i am irreprably messed up.

My lowest BMI was 15.2 and I still had a period. It was regular, too. I've never had any serious health issues with my eating disorder. No blackouts, no fainting, no hair loss, no lanugo, no abnormal blood tests, etc.

I do have osteopenia, however, I could argue that that was/is due to never eating enough veggies/fruits/dairy.

So...I'm either really lucky or my ED isn't as bad as others.
