Hi, Repeatedly counting numbers in your head and doing work accordingly can be suggestive obsession. More details about your symptoms would be needed like do you ever feel that if you don t do things in a particular way, something will go wrong. Do you have recurrent thoughts about cleanliness or do you have recurrent doubts as well? Do you feels such thoughts are intrusive and unwanted and do you try to stop them? You might be suffering from obsessive compulsive disorder. You should consult a psychiatrist for the same. Medications like fluvoxamine will be helpful in your condition. Treatment will exposure and response prevention is also an effective option, provided, someone trained in it is available in your area. Hope this information was useful. Best wishes.
