Not sure if GAM is dead or molting?

My GAM recently started burrowing, and has now gone still. For the last 4 days, she’s been in the same position, not moving at all. She doesn’t smell, no signs of decay, but I’m concerned as even her antennas aren’t moving. Totally still. No loss of colour either. I havent touched her, and don’t plan on it either. Any advice? I’m not sure if she’s dead, or molting. She hasn’t molted since I got her (a year ago,) so maybe she is? Thank you x
