Thanks for your question.
after hearing your problem i understand that you are suffering from obsessive compulsive disorder
where any person have recurrent ,intrusive distressing thoughts or images in his mind and it is ego dystonic that means person want to remove the thought but he couldn't.Same thoughts are coming again and again.
Common obsession are-dirt,checker,washer,sexual etc and as the obsession grows person can do some motor act to neutralize his thought called compulsion.Like you locked your door and that you remember clearly but after going some distance you have hesitation that weather you locked the room it is so intense and recurrent that you come again to check the door here thoughts is obsession and going to home is compulsion.
Obsession compulsion disorder are anxiety
disorder so this kind of patient have co morbid anxiety like you and also panic attack
And your diagnosis is OCD
with pure obsession predominant .You are taking good drug for your disease but if it didn't resolve,same thought come recurrently then you should consult your psychiatrist
he will change the drug or may increase the doses as we usually built clofranil up to 150 mg.
Remember one thing Cognitive behavior therapy acts very well in your disease sometimes more than drugs but it need specially trained doctor and if your doctor is competent in it you can go for it.
But remember one things that drug take at least 4-6 weeks for its full effect so dont be very anxious just wait for 406 weeks then consult your psychiatrist.
