Bed rest legs & measurements

Yesterday was 4 weeks since my last run. Lost most of the muscle in my legs, though my left calf still bulges when I flex. I feel like they're still a lot bigger than they used to be at the start of the year, but the numbers say different. Also did my measurements yesterday, for the first time since I've started to up my intake. My weight is roughly the same (started 47kg/BMI 13.7), maybe a pound lower, but moreorless the same.

Neck 11.5"
Bust 27.5"
Waist 21"
Hips 30.5"
Upper arm (below shoulder) 9"
Upper arm (above elbow) 7.5"
Forearm (below elbow) 8"
Wrist 5"
Thigh (top) 15.5"
Thigh (bottom) 11.5"
Calf (below knee) 11"
Ankle 7.5"

I've lost 0.5" each from my bust, hips (I've always had big hips), upper arm (below shoulder) and calf (below knee), 0.25" from the bottom of my thighs, and 0.75" from the top of my thighs. So 3" total loss in the past four months. To my knowledge, these are the smallest measurements I've ever been. I'm 'smaller' now than I was at 43kg, and I don't have measurements for 41kg. I don't fully understand it, but I'm not complaining.

Will post with more of an update later, just felt like sharing this right now. Not a good day so far at all.
