Fighting could cause HUGE problems for one person and one person only. Three guesses as to who that person is.
If you need to use either of the areas she has asked you to avoid, approach her and politely ask permission, stating why you need to use the area at that particular time. If she says no, politely say "Alright. Thanks, anyway," drop the subject entirely, and continue to obey her rules.

Obey also the Eighth Satanic Rule of the Earth.
Now go release your frustration in the Ritual Chamber, and move on.
