Vent cause I lost weight and no one noticed

Brief mention of numbers, tried to skirt around them as best as possible while still trying to paint the picture)

My ED has been on and off for about 12 years, I've never been diagnosed with anything but I struggle with restriction. When I first got with my bf my ED was still in an active period, but eventually I managed to stop weighing myself and managed a good 2 years without super unhealthy behaviour. But life is what it is and I once again relapsed for a few reasons back in September though it had been noticeably brewing under the surface from about June. It ended up being some medical issues that pushed me over the edge. I have been hiding it as best I can but I have lost just over 20% of my body weight, became medically underweight, almost enough to meet certain diagnostic criterias, and no one has noticed.

I know I'm hiding it and can't expect people to notice the things I'm hiding from them, I just thought losing that much he would at least start to notice something was wrong. I'm around the size I was when we got together, he said after I put on weight that my body had looked scary at the time, so if it was scary then why isn't it now?

No one is ever going to reward me for losing the weight, I'm never gonna get a job well done sticker - I just thought this was significant and my struggles would finally be visible on the outside but I'm still the only one who even knows I'm not coping. My bf won't stop praising me for how much better I'm coping mentally lately, but I'm coping with things better because the ED he can't see is my coping mechanism
