any ideas please help

Hi well where do I start im not sure if im writing this in the correct bit. Im new to this . I suffer from anxiety and depression . But could it be ocd?? Thats the question im asking the doctors do not seem to do anything apart from palm me off with more meds . Basically over a few year I find my self obsessing over people talking about them excessively over and over again this can last anythin from a day to months . Now I find my self still doing the same but also I feel the need to be overly nice because if im not then something bad will happen to me like get sick or even die this makes my anxiety levels shoot up . So any help here I would be thankful for .
