Abuse in any form is wrong and a sin.
Talk to your mother. Tell her in a tactful and loving way that what she is doing is hurting you. Don’t attack what she’s doing but say that she is saying things that are causing you pain and hurting your relationship with her. Pray. Pray for her and for yourself. Find someone you trust to talk to about this situation. Also, you might need to talk to a counselor/pyschologist. Encourage your mother that she needs to talk to someone about her behavior towards you. Have yourself and your mother talk to a priest. If these measure does not resolve things, then move out but not until you have done these things. If you feel that your life is in danger, then move out now but only if you feel that you are in danger of being physically hurt by her.
Now, I don’t know what age you are but if you are over 18, have a safe place you can go, have financial means of supporting yourself, have emotional and spiritual support, then I say leave. Yes, this will hurt the family but your safety is more important than hurt feelings.
Keep a log of when you think your mother is abusing you. Write down days, times, what she says, what you say, your reaction, if there was anybody else present and if they say anything, etc. This is important if you ever have to prove, say in court, that you are being abused.
