Photographer cancels six months before the wedding date!!!!!!!!!!

So I have had my photographer booked for two years and last year i had to postpone my wedding no problem so I schedule my date this time around her schedule originally I wanted June and moved it up to April 6th since that was the day SHE said she had open. She charges $1395 for her base package now and when I hired her she was newa dn only charged $450 so she makes up this long story on how her sisters wedding si the same day and she just found out and can't be there for ours, so she then tells me she booked solid until October so I told her ok I'll postpone to November oh no she says since you booked so long ago you have to book by July...uhm after she just got done telling me she has nothing open until November, really? I have paid her $225 and can't afford to hire another photgrapher at the price I was paying for her that has good quality work I just got lucky the first time sooooo she has given me the option of ONE date 3/9 so what do I do now?
