If she simply breaks the lease agreement, then under the law you may deduct from her deposit for any cleaning or repairs or for unpaid rent as of that date. Additionally, if there is any security deposit money left after the first deductions, you may hold that as well until you get the place re-rented out. You may then take lost rents from the time she moves out to the time you re-rent the place from the deposit. At that time, if there is any money left from the deposit you will have to return it to the tenant.
You will need to rent the unit out as soon as you can and then you can sue her for any lost rents that occurred up to the time that the new tenant takes over the rental---or the end of the 6-month lease---whichever occurs first.
