My larger snakes (eastern and checkered) become seasonal lying good aggressive, but nothing as severe as you describe. (Tong feeding saves my fingers from mis-strikes.)

Moving while latched onto food may work. Some on of my snakes will let go of food if disturbed while eating tho...

If this is the case, place the food in a feeding container and -'encourage' her to enter so you can close up and contain her the way venomous handlers do.

I hope the striking at glass will pass as hormones and seasonal factors change.
Would you consider trying a homeopathic stress relief preparation like aconite or bachelor flower rescue remedy? They work for cats and dogs... not sure how they'd go over in the water dish or sprinkled over food.
