This is ineffective parenting. Being given a sweeping label such as “useless” would make anyone (child or adult) feel bad. As you indicated, it’s making you internalize the remark and feel impotent. Instead of motivating you to do what they want, your parents actually accomplished the opposite and made you feel like giving up.
In psychology, this phenomenon is called “learned helplessness.” After continuously encountering a negative and uncontrollable situation, humans (and animals, too) eventually stop trying to change our condition even when it becomes possible to do so. We gradually surrender and accept our fate. As a result, we may feel hopeless, anxious, and depressed. This is happening to you when you complete your chores but still get called “useless.”
This situation is bound to damage your self-esteem unless you take control. Since you’re already doing your chores, you may be frustrating your parents with too much screen time. If they haven’t set parameters for the use of technology in your home, they should do so as leaders of the household.
Some moms and dads allow screens only when chores and homework are completed. Others allow screens only on the weekend. Still others have their kids put the screens in a basket upon arriving home from school and don’t return them until the next morning. If your parents haven’t set up rules such as these, ask them to do so. Otherwise, misunderstandings, resentment, conflict, and confusion will continue.
It seems like communication has broken down in your family. When that happens, it often results in name-calling. After all, slapping a label on someone is a whole lot easier than making a chore chart, establishing and enforcing screen rules, and being good role models. Yet, all those things are necessary to make a household run smoothly.
