Is my tortoise dead or hybernating?

Ok yeseterday my sulcata tortoise was doing fine. I went to the bathroom and came back and it wasn't moving. Before I went to the bathroom, I checked on it and it was fine. When I came back, it was underneath the heating lamp, with her head in her shell. I work at a pet show, so I told my co workers that my tortoise died "i think" and that I put her outside for the ants too eat, too keep the shell. They said are you sure she's not hybernating? I don't know because I never had a tortoise. After work I went home and checked on her.

No ants were on her, she doesn't stink. Her body parts arn't limp. I touch her head and her to back feet kind of mood. Her shell is a little soft underneath. I don't know what is wrong. I don't know if she is hybernating. I don't even know what happends in hybernation. She is about 2-3 months old. I got her for Christmas.
