I got fired and now I am too scared to tell anyone, even my own family.

It was a Monday morning, and I was at school at one of the meetings when one of the department heads leaned over and asked me how long she had me and I didn't know what she meant. She then asked how long I would be staying at the school. I told her I had the position for the rest of the year and maybe longer. She then told me that my position had been open the entire summer and that the district is going to hire someone else, and they want them to start in a week and a half. They are giving me two weeks' notice that I'm no longer needed and that I have a new principal. I literally freaked the hell out, I told my principal, and he said he didn't know any of that. I asked for a meeting with the department head, the principal, and the district admin. The district admin said that they are aware that I am the only one in the position and that they need to hire someone else, but they can't make me stay. I told them that, unfortunately, it took me three months to get into the position, interview, get hired and start working, I can't just up and quit. I then offered to stay in the position at the school, even if it means not being paid, and they said yes, that's what they were looking for, for me to stay. I asked how long would I have to stay, and they said they would be looking for someone in January. I am now at a point where I can't tell my family because they wanted me to quit since I got the job. They hate my new career and want me to go back to my old one. I've now been at the school for almost four months and I have no clue when or if I will leave. I'm starting to hate teaching, and now I don't know if I even want to continue in the profession. I'm at a point where I don't know what to do anymore.
