Change passwords on all wifi and streaming. Shut off anything nonessential, like cable TV. If you shut off essentials like water or electric that can be construed as illegal eviction so be wary of that. That said, take all your belongings out of common areas and move into bedroom or storage. Nothing says she can use your TV, dishes, toilet paper, dish soap, towels, couch, air freshener, etc. Remove all food and toiletries to your bedroom. Put a lock on your bedroom door.

Be careful who you rent to, and start the eviction process as soon as you are able.
