I would do so. It sounds as though her behaviour is causing you an awful lot of stress.
I'd suggest that if you advertise for a new lodger you consider having some houserules in palce before they move in - that way, you can tell them what the rules/epectations are, ask them if they have any comments or anything they'd want to add, and you are both clear on the expectations from the beginning.
You can explain to any new lodger that you had an unfortuantely exprience with a previus lodger whi behaved very badly adn that that is why you feel it is imprtnat to be upfront from the beginning.
With any luck, it will help to ensure that whoever moves in either has similar expecations or is able to adapt, as they will know before they start both what you expect and that you take it seriously.
