Welcome to HCM
First of all just for your information as you are able to write your problem clearly here and you are accepting your problems so its least likely that you are having some serious mental disorder. Still its possible that you are having some sort of learning disorder
. As in learning disorder (specific learning disorder) individual is mentally normal in most of domains of life, but is deficient in learning some things, like in your case is happening. Other possibility is severe anxiety
which might be creating problem.
And yes treatment of Learning Disorders is possible mainly by psychotherapeutic procedures, special classes etc. In some cases with age disorder improves by own.
So don't worry you will lead normal life you just have to focus on positive things in you and find out in what domain you are good and practice to become best in that particular domain.
Management by many medicines as stimulant drugs, low dose antipsychotic
drugs improves the situation.
Hope I cleared your doubt.
