You cope by being proactive. I'm so glad you read the article and now understand the seriousness of parental verbal abuse. Please talk to a trusted adult immediately about what's happening in your home and how it's affecting your mental well-being. Discuss it with a school counselor, a grandparent, a teacher, a neighbor. Show them the research in neuroscience that explains how name-calling has the potential to alter the structure of the brain, having a negative impact for years to come.
Parental verbal abuse is typically a symptom of larger problems in the home. You, your parents, and your siblings may need to attend family counseling together. Your mom and dad may need to attend parenting classes. You may need to see a therapist. You may need to live somewhere else until the situation in the house improves. Your parent is off track and needs some help to do better.
Start taking better care of your mental and physical health. Spend time with friends. Share with them what's going on and how it's affecting you. The worst thing you can do is keep your emotions bottled up, causing you undue anguish. Focus on exercising, eating right, meditating, and spending time in nature. Write about your feelings and experiences in a journal.
Most importantly, don't try to handle this by yourself. Reach out to someone right away and keep reaching out until someone hears you and helps you. I'm keeping you in my thoughts and hoping for the best.
