Sorry to say you are wrong in your approach to the said case.She is your wife and she is ill.You are ignorant of her signs and symptoms and so have been the treating doctors.OCD(OBSESSIVE COMPULSIVE DISORDER ) is very much a treatable entity 30 TO 40 % CASES CAN LEAD AGOOD LIFE ..Be kind to her .OCD illness manifests with following symptoms ARE THEY PRESENT IN HER
Obsession -Repeated intrusive thoughts of own which patient recognizes as her own in form of dirt/doubt/slowness/order
Compulsion - Acts which are performed t by patient to reduce the anxiety that builds up likef washing/checking/arranging things in particular order.Pt ususally knows what they are doing is senseless but are compelled to follow thier repeated intrusive thoughts with abehhaviour like chicking/washing etc or they get tense.There is usually no fits in them .
You have written at several place what she does but never mentioned what medicine she takes.I think you are very much ignorant and you never applied yourself to treat her well.You are shifting the responsibility Its not advisable.OCD can hit any body in stressful periods of like
change of job
added resposibility in new house hold
Why she should have "fits".Is it neurological seizure or hysterical seizure.I understand that your dream of married life is destroyed .But get her treated .You cannot undo the past.People might have hidden the illness but dont blame her for crulty if she is not treated properly.Do you have her treatment records of being ill before marraige.If not then dont think that she is having it before marriage. Document your efforts of getting her treated and take the responsibility .After you have tried and failed or she is unwilling to accept her illness then only you think of divorce otherwise not.Its not right as per my perception.
