...lets take a look at some of the ADHD traits that cause all of these problems:
ADHDers usually have poor self-esteem and ego structures. They often dont feel good about themselves for this reason and their self-doubts keep them from effectively developing winning personalities and taking part in social events.
Teen and adult ADHDers often feel they are not in control of their own lives and as a consequence dont take criticism or advice well. They can develop paranoid thinking as others are trying to manipulate them, because while they were ages 5 to 15, classmates, friends, parents and teachers usually manipulated them to try to change their behavior or get them to do what they wished.
They sometimes feel as if they are dumb or stupid because their inability to focus or pay attention to details of a task and complete an assignment leads to frustration and self-doubt.
ADHDers inability to effectively integrate, absorb, process, and communicate input from visual, auditory (sound) and tactile (touch) sources often leads to confusion and frustration if they are expected to respond very rapidly to an event or question. Just like the rest of us, if we dont understand a situation, we become confused, perplexed and frustrated until we can resolve the issue. Unfortunately, ADHD teens and adults process these inputs (vision, sound, touch) much slower, have problems thinking through and analyzing an event and cant effectively store the processed information once it is processed. As a result of these observations, we often say ADHDers have problems with executive thinking or the executive processing centers of the brain. In addition, their problems with executive thought processing causes communication difficulties resulting in even more frustration.
