I think I might get fired from my job, Help?

I am currently having a family crisis. I recently have had a family crisis and it is taking a toll on me. I went into work when day with every intention of working, but upon arriving at my place of work I broke down, because of what was going on in my family and was not able to work. I was crying hysterically and having an anxiety attack. I went to talk to my manager to let her know that I was having a family crisis and did not want to give her much detail, because it is very personal and I felt she did not need to know. When I approached her her first sentence was "Are you ******* kidding me." I felt this was uncalled for, but I did not say anything at the time. The conversation continued and I was sent home. I was in such as state that I was not able to drive myself home and was picked up. I have now recently heard that I may be fired. I feel this is unjust. I also feel her use of language was highly inappropriate and should not have been said. My question is can I be fired for leaving work because of the family matter at hand? Also is there anything that I can do for her use of language towards me?
