stessing out, money is tight

have been having so many problems with our landlord that we had to hold rent before they even attempted to take care of some major issues about the apartment. It has been three months and still they have not fixed everything and now there are more issues. The most important of concerns are that our porch which is our second eagress has a cease and disist order on it and has been there since the end of summer and that both of the kids windows have huge cracks in them. Today we were given a demand for rent or else an eviction process will start. I have to talk to my lawyer because I am not sure what my rights are. Still stressing out though.
