It's important to note that I don't have the full context of your situation, and whether something is considered abusive can depend on various factors, including cultural norms and individual sensitivities.
However, in general, repeatedly yelling, blaming, and being unnecessarily cruel can be emotionally harmful and detrimental to your well-being, especially when you are already dealing with challenges like ADHD, anxiety, and CPTSD. It is natural for parents to be concerned about their children's success and well-being, but expressing that concern through abusive behavior is not appropriate or effective.
It is crucial to have a supportive and understanding environment when dealing with mental health challenges. Your struggles with ADHD, anxiety, and CPTSD are not your fault, and they are not something you can control entirely on your own. Instead of resorting to cruelty, your mother should consider seeking professional help, such as therapy or counseling, for both you and her, to better understand and cope with these challenges together.
If you are experiencing emotional abuse or find it difficult to communicate with your mother about her behavior, consider reaching out to a trusted adult, teacher, counselor, or mental health professional for guidance and support. They may be able to provide you with resources and assistance to address the situation effectively.
Remember that your mental health is essential, and seeking help from caring individuals can make a significant difference in your journey to success and well-being.
