You should consult a psychiatrist
Detailed Answer:
Hi
Thanks for using healthcare magic. I, Dr Abhishek Kapoor, would help you in this query.
The symptoms, who have mentioned, are more towards
ADHD. In that case, whether you need medication or not, that depends upon the severity. ADHD is childhood onset disorder and with age, its severity decreases. That means, may be at childhood you would have more severity than now. ADHD normally effects on concentration, that why you are feeling difficulty in making concentration. It is not due to laziness.
You should consult a psychiatrist for proper assessment and evaluation. There are certain medicine like
methylphenidate or
atomoxetine that would help to control symptoms, but there dosage depends upon the severity and these drugs are not available over the counter.
There are certain techniques which you could follow like draw a circle on paper and color it, try to put beads on thread, mix any of two pulses and try to separate them etc. These techniques would increase concentration and sitting power.
In case, you need further help, you can ask.
