Hello respected sir/madam, My name is Abdul. I am 28 years old. I am working professional and preparing for competitive exams in my part time. While studying I am not been able to concentrate on it in a wholesome level. For suppose, if I started to study a topic after 10 to 15 minutes or so some creative thoughts start coming in my mind and I get lost in them. Also, sometimes I read the sentences verbally but I am not mentally present in there. This has been a mess since a long time. Earlier I took some of the medications for it through several psychiatrists but after 1 year or so the problem faded and from then onwards I didn't went back. Initially it was all so good and happy kind of. No anger, no irritative behaviour or overthinking. I was at calm and peace. But then suddenly recently I am experiencing such instances of this symptoms. This has taken a toll in my life. Not been present mentally anywhere. Just lost in stories and thoughts. I have exams in some days now. Please help.
