Wow, Nelly! 76 lbs! My sister (she doesn't have IBS) was similarly underweight in high school and she did receive a lot of rude comments and people assuming she had an eating disorder or a worm. We laugh about it now, but I remember how upset she was at the time. It's unbelievable how insensitive people can be.
Now that I've experienced being underweight, I can understand a bit better how terrible those assumptions can make you feel. I've also learned that the less you weigh the more pain you feel! I'm uncoordinated, but since I used to have more padding, other than feeling embarrassed I didn't feel much pain. Now I feel every bump and stumble, every blow I take to my hips or elbows.
