Dear
Welcome to HCM
We understand your concerns
I went through your details. I suggest you not to worry much. Poor concentration in study is mainly due to lack of proper aim and planning. If you are not serious about your future, how can you perform? How can you study seriously?
Every person in the world study hard just days before examination. At that moment, there will not be any boredom, loss of concentration, low appetite etc. Because their aim is to study to pass the examination. I know, in your case also, this should be true.
All other symptoms you mentioned are just due to
anxiety and apprehensive thoughts you created related to the low concentration. You need career and education counseling.
Please post a direct question to me in this website. Make sure that you include every minute details possible. I shall provide you career and education counseling. I shall also prescribe some
psychotherapy study techniques which should help you cure your condition.
Hope this answers your query. Available for further clarifications.
Good luck.
