Hi guys. Sorry if I'm posting this in the wrong section, I'm fairly new!

My question is, is my bp stressed? And how can I tell if she is becoming stressed? How can I tell if she is content? She is approx. 1ft 9in , and approx 205 grams.
She is currently in a 50 gal terrarium with three of the sides darkened. I have a large branch that stretches across her enclose and stretches up. She is ALWAYS on the stick, in the middle of the terrarium. Sometimes she loosely balls up and rests with her head on top of her coils, and sometimes she lounges stretched out over the stick. I have a hide directly under her heat lamp, and one in the middle (because I noticed that's where she appears most comfortable) and when she leaves the stick she goes the the hide in the middle. My temps are at 88( approx) and 77 (approx) I have yet to feed her as I've only had her three days. Her next feeding time is next Friday.

Thanks for all help and advice!! Here is a pic of her currently
