rehire status

I am disappointed in my old job. I worked there for a year and they always told me that I was one of the best they had. (Not to brag) But I wonder if that was just a bunch of crap to keep me there. There was a virus that went around and I caught it. I have diabetes so if I get sick I am knocked on my feet. I worked through most of it but at the end I about fell out. I wanted to ask for a few days off to get better but everyone else who got sick beat me to it. I went to my director and told her that I was sick and I could not do it anymore. She asked me to giver her to weeks and I would have of COARSE but I physically could not do it through the illness. I was afraid that I would get yelled at for asking for days off. It was my mistake to quit I guess but I was so warned down I just was not thinking straight. Well, I found out that my rehire status is no. Which means that I can not even use them for a reference. They are all I have because for 10 years before I worked there I was a homemaker. The old assistant director saw me a few weeks after I quit and told me that if I ever wanted to come back I could. The new director who is a real pompous ass did not want to listen to anything I had to say. She just said she upholds there policy that if someone quits without 2 weeks notice they are a do not rehire or what ever. Oh and one more thing, two of our residents died due to this illness. They treated me like crap. They knew I was sick too but made me take over everyone elses hallway while they went home and rested! I have an appointment with a lawer this morning but it is so expensive to sue. I dont even know if I can to tell you the truth. I never went to the doctor. This is the 3rd virus I had gotton sick from, from that facility.
