In limbo here, need advise

I missed a week in a job while still on probation. My father is ill and I am his primary caretaker. My supervisor was on vacation and I called in every day. The last day I called in my supervisor was on vacation. His supervisor, HIS MOTHER then called me to find out why I did not call. I told her I had left a message for him, (which I had done everyday that I was out). She told me that he was on vacation. She then told me to let her know when I would be back to work and gave me her cell. I called her the next morning told her my dad was out of the hospital and she told me I would not be coming back to the clinic I was in because the dr. was upset by the time of my absence. She told me she would be placing me in another clinic. I have heard nothing since, she will not return my calls. I don't know what to do. I am so stressed. I also have a disabled husband who is pressuring me about the money I am not making. I have had to quit 2 jobs because of my dad, but he was doing well for awhile and I need to work. Anyone have any advise?
