So, not very conscious but nevertheless we are here to help eachother out!
Be calm, your ball python can still resist 3 days, but don't let it be in that kind of situation for the good of you both. 65 as room temperature is not the best, it will surtantly not kill the snake but it will do it no good either. If it ate then there is no major problem, just make sure she doesn't escape and she doesn't burn herself, as soon as you get the rest, set everything up and enjoy your ball python.
