I think I shocked my Persian lime tree. Is there anything I can do to help?

I got her a few weeks ago for a container tree. She was outside before the cold snap we had recently but I brought her inside for that and then put her back out when it warmed up and nights weren’t getting down to freezing. Maybe one night just got too cold that I wasn’t aware of. I’m not sure but I noticed her leaves were yellowing/drying after a few days outside. I’ve brought her back inside for now and she’s looking worse and worse. Should I keep her inside until spring? Anything else I can do?
