#ksb help

She has gone two weeks without food. Last time she was weighd she was at 280g and I've been feeding her medium mice. I switched her substrate about 3 weeks ago to half aspen and half repti chips. She started glass surfing and trying to escape shortly afterward. A week later, after she refused her first meal in 2 years I switched her back to only aspen. It's been a week and she's refused again. He temps are roughly 98 on the warm side, and 73ish on the cool side. She's in a 20gal long and has been there for over a year. I'm really stressing out about this so if anyone has sand boa female advice I would greatly appreciate it.
