I'm 18 and I've litterally only had this for a week. My mind simply won't shut up. Continuous day in day out rapid thoughts and songs. I've litterally only had this for a week and it's already driving my crazy. I've heard some people have the opposite and have a blank mind? Any advice? I've been on sertaline for 2 years and only ever felt like this while in a panic attack - once it ends so does the feeling. Constantly tired and off balance for no reason, there's also a constant sickly feeling like im going to vomit but nothing every happens. Thanks.
