I have suffered from anxiety for a couple years now and just recently I am having issues with invasive thoughts. My thoughts will start racing incredibly fast and I will get random songs, phrases, or conversations stuck in my head and I don't know how to make it go away. I get scared and go into full panic mode and feel like I'm going crazy and it makes me want to cry and sometimes it makes it impossible to concentrate or sleep. I know it's just anxiety but I don't know what to do and I need reassurance that I will be okay. Does someone else experience this? What can I do?
