If I had court today and the landlord showed up at my door and said I have until tomorrow to get out with no notice, can she do this?

Did you have court regarding a forcible detainer action your landlord filed against you?  If it was court abouit something else, then no, your landlord can not evict you in this fashion.  She needs to give you a five-day notice and then file a forcible detainer action to evict you.
