Recommend Treatment For Writers Cramps

hello doctor. I am 20 years and am pursuing my law graduation course. last year i had problems in writing during my board exams. doctors declared it writer's cramps. Also before that since last four years i am finding it difficult to concentrate on my studies. I am losing interest from every thing which once was my passion. my days pass on with nothing. I've started avoiding people and even friends. I was an all-rounder and a very bright student till 10th at school. then gradually my life seemed to me worthless, hopeless and useless. Once i was considered to be a powerful speaker in my school but now the situation is that i find it hard sometimes to put my simplest talk, even to my friends and family members. its badly affecting my academics and my life as a budding law professional. my concentration fluctuates and during exams i remain very uncertain for it. i am very worried. i tried all my best to handle it all but i lose it every time. is writes's cramps too associated with it. is there a treatment?
