Dear Welcome to HCM We understand your concerns I went through your details. I suggest you not to worry much. First of all, I don t understand why you are taking or tried anti depressants? Are they prescribed? If they are prescribed, why did you consulted a psychiatrist for this concentration problem? For just concentration problem, no psychiatrist shall prescribe anti-depressants. Is there anything else? Low concentration is due to mental stress and fatigue. Mental fatigue is real. Brain is not suitable to think and work continuously more than around 1 hour. It needs rest pleasure. It needs to be relaxed. Now a days, a lot of companies introduce relaxation exercises or procedure during work hours. I think you should think about them. Please provide enough rest to the brain. Relax in between job hours. Talk to others, go for walk inside the company premises, play games after finishing work, do exercises in the morning etc,. Weekly outing with family and friends also helps in relaxation. Please understand,. Human brain is enough to any process, you name it, and it will do it for you. But it needs proper relaxation, food and leisure time. If you require more of my help in this aspect, Please post a direct question to me in this website. Make sure that you include every minute details possible. I shall prescribe some psychotherapy techniques which should help you cure your condition further. Hope this answers your query. Available for further clarifications. Good luck.
