Doublecheck the temps and make sure she can thermoregulate. If she is really active, it might be a sign that she is restless, something is bothering her.
Does she have hides in both the warm and cooler end of the cage? I find that hides are very important for Ball PYthons.
Also, if she just shed, she might not have been hungry because of that.
Since she has not eaten for 2 month though, i would think there is something else going on.
If the husbandry is correct, perhaps you are handling her to much/to often?
I would just leave her alone as much as possible till she eats reliably again.
Try to put the frozen/thawed prey into her hidebox with her at night, and then don't disturb her till morning.
If that doesn't work, leave her alone and try again a week later.
Don't try to feed to often, you might stress her out more.
Sometimes ball pythons just stop eating for awhile for no particular reason, so if everything is as it should be and she STILL won't eat...just try every week or so, and don't worry about it to much UNLESS she is showing signs of disease or she is losing weight.
