Dear Welcome to HCM We understand your concerns I went through your details. I suggest you not to worry much. The surgery and your inability to cry may not be related. From the given symptoms, paranoia can be diagnosed. But that is not all. These symptoms also could manifest if you are stressed, hugely disappointed or obsessing these thoughts. Therefore differential diagnosis is required which can only be provided by a trained psychologist / psychiatrist. Researches proves that medicines alone cannot cure anxiety disorder. Along with medicine you should practice psychotherapy techniques to streamline your life style and meditation and yoga techniques to calm your mind, body, streamline your metabolism and thinking style. Please consult a psychologist. If you still need my help, please describe the whole problem in detail and post a direct question to me. I shall definitely help you with psychotherapy techniques to over come your problems. Hope this answers your query. Available for further clarifications. Good luck.
