If you or someone you know is experiencing this kind of abuse, it's essential to seek help and support immediately. Talk to a trusted friend, family member, or counselor about the situation. Additionally, there are organizations and helplines dedicated to assisting individuals facing abuse, such as domestic violence hotlines and local support groups. Remember, your safety and well-being are of utmost importance, and there are resources available to help you through difficult situations like this.
