The situation you describe may not necessarily fall under child abuse, as you are an adult at the age of 20, and child protective services (CPS) typically deals with cases involving minors. However, if you believe you are facing an unsafe or abusive environment, there might be other resources available to you.
If you are concerned about your well-being and safety, consider reaching out to social services or a local support organization that deals with housing and employment issues. They can provide guidance, resources, and assistance to individuals facing challenges like finding a job or securing housing.
It's also essential to have open and honest communication with your parents. Try discussing your concerns and your efforts to find a job. Express your willingness to contribute to the household and your plans for independence. Showing that you are taking the situation seriously and making an effort may help improve the communication between you and your dad.
Remember, each situation is unique, and the best course of action may vary depending on the circumstances. Seek guidance from professionals or support organizations to assess your specific situation and determine the most appropriate steps to take.
