Please, keep in mind we only want to help. You seem like you're getting a little defensive, which is understandable, but please don't shut us out. I am sorry if suggesting a burn was offensive to you as you obviously care about your snake but we are trying to get to the bottom of the problem so we can help you.
99 does seem too hot and 63 way too cold!
Also how old is she that you only offered prey every 2 weeks?
Most people will say that a young (under 6 months to a year) ball should be offered food every 5-7 days, and older balls should be offered food every 7-10 days.
Also you mentioned another snake, I think? ...They aren't being housed in the same enclosure together, are they? If so then that would be the likely cause of why your snake isn't eating.
Good luck
