What's up with my girl

[Shaiza]

My girl is unknown age (rescue from Craigslist). She's about 3-4 feet long now. Had her for maybe 7months now. Usually she's a very active snake to the point of making me up. Usually fine being held.

Over the last week she's been dormant. Only ever in her hides. Took her out to check her and she was not having it. Thought she was blue but she shed 2 weeks ago. She's been shedding a lot recently too. Once a month about.

So I'm not sure what's up with her and I'm worried. I did add a small uth as the room was a little cold over winter. Temps on the warm side are 82 and cold side 70-75. Day night cycle is sort of inconsistent. I work nights.

Any help would be appreciated. I love my trash baby
