My 1.5 - 2" GBB's been in a weird half curl recently sitting on its hammock. Worried that it might have been dehydration, last night I dropped a few drops of water on the web. Other than being startled initially, she seemed to drink from it so I was relieved and went to bed. This morning she was on the ground and stayed motionless the whole day, I stopped to check on her a few times but she didn't really move but at least wasn't wasn't curling.
This evening I checked again and was shocked to see she had lost her two back legs! I'm completely devastated. I've never seen T's lose two legs like that before. What could be the issue here? Is it dehydration? starvation? Was it a fall? Is this a bad molt? She did reject food last week when I tried feeding so I suspect maybe pre-molt. What's going on? Should I do something or just leave her alone?

Sounds like she had a bad molt, this could occur from a previous bad molt as the T removes the appendages that were not properly formed in previous molt. Just keep a close eye on her, keep trying to feed her at least once a week, make sure she has plenty of ambient humidity by keeping water dish full as well as misting lightly on one side of the enclosure. As long as she has her fangs and has eaten, the blood should clot if there was any bleeding. Worse case scenario, if you do see any signs of hemolymph, then you can mix corn starch with water and patch up the wounds with that solution. Other than that she should be fine. I pray she makes it through.
