Hello miss. Good morning. I read ur description about ur condition for these years. I wud like to comment over few issues that you must understand before jumping to any conclusion. You have vaguely informed 4 issue, I will illustrate again to make it simple for both of us. 1. Concentration and memory problem. 2. Interest and motivation. 3. Mood dysfunction & Anxious feeling. 4. Emotions turmoil and behavioral changes in     form of anger. 1. Concentration : means prolonged attention, it is genuine to loose prolonged attention towards anything for hrs, as mind runs too many "thoughts " at a time. But, it absolutely not genuine if someone is unable to sustain attention for seconds and minutes. Thoughts that hampers ur concentration can be in form of worries, fear, apphrension, negative thoughts, images, situations and many more. These thoughts continuously alter you focus from present and push in past or future or nowhere. As you mind don't get enough focus over anything so it is unable to store or create memory for it, thus you feel that you have a memory problem but actually it's concentration problem. 2. Interest and motivation : are absent when ur mind don't have clear steps of achieving ur desired goals or life. Mind has a habbit of accepting things in pattern ,if random or puzzled ideas or plan is present ,mind get problem in processing such plans thus ,u often don't see solutions for ur desired goals and finally loose interest and motivation from that process. 3.Mood disorder & anxiety disorder : also cause impairment of concentration , interest and motivation. 4. Emotions and behavioral expression : depends variably upon above discussed issue , personality, psychosocial stressors or any other illness.
