Get your personal life in order. Look at yourself and try to see from your bosses point of view why he fired you. It will make you mad. But you can't let it. You need to dust yourself off, organize your clothes, your paperwork, your resume. GO GET THE NEXT JOB. When the interviewer asks why you left your last job, say "I would never speak badly about my previous employer, but I will say that my departure had nothing to do with my productivity or dependability."

You have to tread carefully at home. They will kick you out soon if you aren't careful.

You have to start detaching from these people that you are living with. Consider them a minor inconvenience that you have to deal with while you look for a new job. After you get the new job, organize your finances and move out.

Right now, you need someone to take care of you. But it doesn't have to be that way. The people taking care of you are poisonous. Tread carefully, start detaching emotionally, get a new job, then move out. They will fade into memory, and you will have a new life.

YOU CAN DO IT. Sure, you may not have all the conveniences of a big screen TV and a dishwasher or whatever. That all takes saving up over time. But what you will gain will be much greater than all of that instant material possessions. You will be free from abuse and dependence.

In my opinion.
