Being new to tarantula keeping I had to fight the urge to dig her up, to see! All the advice is, "Leave them, they do this, bury themselves and don't eat." But it's hard. Well, after 24 days of not knowing if she was alive or even still in there, I was a little worried she might have escaped, I finally have confirmation she's alive and in her enclosure! Overnight she took a pre-killed cricket!
