I'm really confused and worried about my girl who maybe about and hour ago seemed like she was about to die.

Out of all my snakes she is one of the perfect ones, always healthy appetite since a hatchling,and no prior strange behaviors.No bubble breathing or whistling except during shed time, shes had no history of being sick and only snake I've ever have a respiratory infection was about 2 years ago and none since.

Earlier this week I had a major power issue , after feeding everyone on Saturday something in our meter box burned out and left sections of the house without power, this was all while I was sleep, so my couple racks were without power for a good 8 to 10 hours. A few extension cords later I made sure I got heat back to my snakes first but I wasn't sure if that time without heat would affect their ability to digest as the temps had dropped to mid/low 70's. I kept a close eye on everyone and all seemed fine but my one Enchi girl still seemed like she had a lump in her, but it was a bit farther down her body and I kind of assumed it was just a feces mass.

Tonight I started hearing noise in her tub, first the usual knocking over of her bowl, then a few minutes later sounded like choking noises.
When I opened her tub she came shooting out like she was trying to escape something, and her belly looked bigger , at least from the angle I was holding her.
I filled the bathroom sink with very warm water and tried to set her in it, she seemed bent on trying escape and seemed a bit uncoordinated in her efforts like panicked flailing, and every few minutes she would pause, open her mouth and make like a forced belching sound as if trying to regurge, she seemed to be straining as well.
I got her to calm down a bit but I think it was her own exhaustion. she laid in the water and just seemed very limp and unresponsive, I rubbed down her belly gently feeling for any hard lumps but it felt mostly normal, almost airy, but I did manage to work some feces out of her system but she didn't really seem to improve much.I could pick her head up slightly and she would just hang there, maybe slightly pull back.
What scared me the most was when she seemed to be having the snake equivelant of a seizure , she coiled up really hard on herself, her mouth open and turning deep pink from the strain before she relaxed again but this time she was completely uncoordinated and for brief moments her tongue would hang out her mouth. I literally thought she was going to die right here and now. She went limp again and just laid there with her mouth partially open, I kept most of her body in the water except her head and she just laid there for bout 20 minutes, slowly regaining her bearings. Once she finally came out of it all she seems back to normal. Normal tongue flicking/alertness as f nothing happened.

I've been keeping her around my neck and she doesn't seem in a hurry to leave. I'm trying to keep her a bit warmer for a while without having to turn the whole racks' heat up on everyone else.

Sorry for this huge text block but I'm really not sure what just took place here. I have never had a issue with her since I've had her and this just happening out of the blue is a major curve ball. I'm thinking of skipping a feeding for her just so her system can completely empty out.
