The symptoms you describe are similar to symptoms of paranoid schizophrenia, but the issue is that schizophrenic people are not aware of their condition and they don’t ask for medical help (or questions) on their own. People diagnosed with schizophrenia are usually brought to a mental institution by force when their behavior becomes intolerable to their family or society. It seems likely that your condition is more neurotic than psychotic, but you can consult a mental health doctor for an expert opinion.
