Dear Welcome to HCM We understand your concerns I went through your details. I suggest you not to worry much. The change in behavior could be due to so many factors like the drugs used, anxiety and depression before, during and after the surgery etc. The effects of drugs shall slowly vanish within some days, if the drugs are not repeated. You should check with the doctors about this. Regarding mental anxiety and depression, such a state came out of natural negative thinking about the ensuing event. Such thoughts are always there with a patient who is at fate s mercy. Therefore, it might take a lot of time to recover and some times psychiatric intervention may become a necessary. The recovery is totally dependent on the patient s attitude itself. Prayer and patients belief always pays. If you require more of my help in this aspect, Please post a direct question to me in this website. Make sure that you include every minute details possible. I shall prescribe some psychotherapy techniques which should help you cure your condition further. Hope this answers your query. Available for further clarifications. Good luck.
