To properly answer this question would require a review of your lease agreement. That said, there may not be an "out" built into the agreement as it was written by the landlord, not you. You may want to talk to the landlord and explain the situation bu not before you discover what is causing the attacks first. If there is an uncorrectable health issue with the property it might be the leverage you need for your escape.
