Robin always gives amazing advice
I would just like to add by saying, if your mom is making threats, then she is definitely abusing you and breaking the law. My advice is to you is to record everything she says to you. Time, date, thing that was said, etc. Also, get a recorder. If you ever need to go to the police, you'll have evidence. I highly encourage you to go to the police if you feel you're safety is threatened.

Take care, and good luck on your job opportunities
