I did and it was horrible, though the type
of horrible that you accept to be normal. I was 5’8 and 110 lbs. you get brain fog, no energy, even lose periods sometimes. makes you act and feel like a fucking zombie. i had bad breath, was constantly cold. at a certain point I didn’t even care about my weight or appearance, just a feeling of starving and looking sickly. I’m 135 lbs now and still slim, just not super bony.
