Dear Welcome to HCM We understand your concerns I went through your details. I suggest you not to worry much. The basic symptom every OCD patient shows is that of a doubtful approach in anything and everything. You are also showing the same. You should never worry about sickness, disease and death because you have no control over them. You can hope for the best and do your duty like doing exercise, being fit, eat good and nutritious food etc. But still you cannot control these three and also your future. That is basic. In OCD, you are always obsessed to thoughts and activities. Minor OCD, everyone have. When it goes beyond control, it is bad. Medicine Zoloft is good for OCD, prevents intrusive thoughts. Therefore you should obey your psychiatrist and starting the drug. Your psychiatrist knows your condition well and he is good judge. Trust him and you will be alright. 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. Hope this answers your query. Available for further clarifications. Good luck.
