My friend Megha is currently suffering from anxiety and she is also unable to stop thinking on some topic. Around 2 year ago, She consulted a doctor and he told us that she was suffering from OCD and anxiety and her medication started. 6 month ago she again consulted with some other Dr. And he say that she don't have OCD but confirms anxiety. Now her condition is becoming worse she is unable to stop thinking about some topic. 2 months ago she have a thought that someone will change the books that she is studying so that she will fail Now a days she is thinking that her sister and boyfriend are in relation. The thought of books changing is now okay she manages it But her sister and boyfriend relationship thing she is unable to get of her mind (His boyfriend and sister both makes her understand that not truth but she says that she knows but unable to stop thinking) Please help.
