Hello. I'm a ca student. I hv failed in ca ipce two time nd now im preparing for third attempt. But now I can not study well as before. I can not study even an hour regularly. My mind think too much but not concentrate in books. My mind is not want to study however my exam start from 4th april. Im afraid too much. My eyes become sunken, the cheek bones protrude and black rim round the eyes. What to do for my mind and my physical health.
