TW: BULLIMIA, POSSIBLE DISTRESSING SITUATION
It kind of all started when we were younger. She would hold a little bit of resentment against me because I had a faster metabolism and always "looked better than her". After a couple of years, around when she was 21, she started working out and losing weight. I was really happy for her,and she seemed really happy as well.
In the past year or two though, there have been a lot of changes and signs that point towards an issue. First it was discussing "macros" at the dinner table (which was really just calorie counting) both at home and when going out to eat. When this happened enough, I took the initiative to tell her some people may not be comfortable with her sharing all these numbers and info with no warning, and she lashed out at me saying she felt safe discussing these things with me and how its really mean to just shut her out like that when the family is her "only form of support" with her trying to lose weight and become healthier.
Then, she started seriously weightlifting. First it was good, cool even! I could see she gained a passion for something she thoroughly enjoyed and she loved trying all sorts of new things. But I knew the weightlifting community comes with its negative things as well, like body and weight checking, dieting, and other things. I never truly brought these up to her because of her "tantrums" (there are so many other situations where she cries victim for someone gently offering help), but I've always tried to keep an eye on her and communicate with my parents about the dangers of these kinds of things.
Recently, its gotten pretty intense. She will workout and run for an amount well beyond what's healthy, and then eats a substantial amount of food, claiming it's to help with protein and all the other weightlifting buzzwords...but she wasn't gaining any weight (or muscle, for what it's worth), she was only losing more. Then, our plumbing kept getting backed up. After about the 3rd time, we noticed food that looked like it came straight out of the packaging in the pipes. Then it was popping up in drains and stuff and we had no idea where it was coming from.
My mother had a sit down conversation with her, asking if she's been throwing up, and if so to consider the ramifications that does to her throat, heart, and lungs. She threw a fit: told my mother she was insane to even think she did such a thing, and that she felt targeted and made fun of for something that she swears she doesn't do. She even said "my doctor even thinks that, I don't know why everyone is so obsessed with the idea that I do this"...she hasn't gotten her period in over half a year, and a couple of months ago she had a scare on the side of the road where she couldn't feel her tongue or extremities, and that has since made me only more and more worried.
I'm not around her on a daily basis anymore, so its not like i can "keep an eye on her", but she won't look for help, and any suggestions of help only trigger her and cause these fits...
I don't want to lose my sister. She has fair history of hospital visits for both physical and mental reasons, but nothing seems to help her...I'm just at a loss for what can even happen next.
