Hello, As per the description provided by you here it is highly suggestive of a mood disorder like depression or dysthymia. However the kind of symptoms that you have described will require a comprehensive assessment and understanding. The problems will need to be understood not just as a label or a diagnosis, but rather in Bio-Psycho-Social context where efforts will be made to understand your personality, environmental attributes, coping skills and defence mechanism, and medical issues. In short, a understanding of you as a person will help manage your condition better, and also be able to prevent such problems in future and also promote psychological growth of yours as a person. Hence my advice for you is to seek consultation with a psychiatrist near you for assessment and management. In addition to medication psychological intervention is likely to be required to help you. Hope this helps you. Best wishes for health and future.

Hi, i feel all of this is because you underwent certain hormonal changes during that age(puberty). i suggest you start eating well and doing regular exercise. also visit a psychologist and get further evaluated. take care

Our life though is continuous, consists of multiple phases. Teen years, which are accompanied by the onset of puberty can be considered the most important phase of one's life. In this phase, we change in many ways. When the puberty hits, it's accompanied by a sudden surge in hormones. These hormones not just act on us physically but also affect our thoughts & emotions. You were a person who had placed a lot of importance on excelling in academics. Your attention as well as activities revolved primarily around studies. This must have reflected even in the circle you associated with or friends you chose. After puberty your hormones started to alter your focus in the way you couldn't comprehend or cope with. After 2 years when you could bring yourself back to the academics oriented mindset, you would have already developed some tendencies & habits which are draining your energy quickly leading to a state of reduced focus accompanied by fatigue. At this point it is more about getting thoroughly evaluated physiologically for any hormone imbalance followed by gaining the right understanding of your unique experiencing to come up with next steps. Please consult a psychiatrist or psychologist with priority. I am sure you must have done a lot of research on net about both depression & ADHD. You might carry few ADHD symptoms or some depression symptoms however end of the day, it's about addressing the difficulties you have been facing in a competent way & to bring back your control on your life. Good Luck.
