Well you temps are off so I would also try to correct that 80-84 on the cool side and 90-94 on the warm side (measured with a Digital thermometer, not a dial)

Also keep the temps constant - NO night drop.

Try making all those small adjustment and leave her alone for a week (NO HANDLING) than offer a prey slightly smaller than the girth size.

If she eats, I would still advise you not to handle her as often, at least not until she eats with consistency.
