I’m sorry that this is happening to you. Your mother is using poor judgment and is lacking self-control. Her behavior is verbally abusive. Hopefully, you can convince her to stop but, if not, please get an adult involved to help.
When she’s in a relaxed mood, bring it up using “I messages.” Say something such as: “Mom, I feel sad when you call me names. I’m worried about you. It seems like you're under a lot of stress and I’m wondering if there’s anything that I can do to help.”
By expressing compassion and concern, you might prompt her to open and be vulnerable. It might be the starting point for a much-needed conversation about what’s happening in your home. Then, the two of you can brainstorm ideas to fix it.
If the name calling continues, talk with an adult you trust: your dad, a grandparent, a teacher, a family friend, or a counselor. Ask that person to intervene on your behalf and speak with your mom. She may be at a breaking point and need some support. Take good care of yourself!
