<s>[INST] Hi, im a freshman in highschool but lately i ve been having a lot of problems with reading, or looking at screens, and also writing. I cannot concentrate on what i m doing because I daydream or I get headaches after a while, so I have to read it over and it is hurting my grades. When I write i ve been mixing up letters so I have to erase and write again. I can t concentrate on pwoer points and it is getting hard to take notes because when I look it hurts my head after a few minutes, or I just zone out so I can t write them down. My teacher thinks I may have dyslexia , help? [/INST] Hello The symptoms you have described as poor concentration, day Chat Doctor.  While writing you have problem of mixing letters, and you have to erase and write again. It may occur due to dyslexia, but dyslexia is common in childhood and less common in high school. It may occur because of mild form of depression. Mild form of depression may present with poor concentration, poor performance in studies. It may be a sign of early stages of OCD. As you have problem of writing and erasing words, it may be a feature of OCD. But for definitive diagnosis detailed evaluation is needed. I will advise you to please visit a good Psychiatrist for evaluation. Thanks </s>
