Hi, 3 weeks ago my friend told me that he had cancer, but it was all a lie to get attention, when suddenly he told me that, I got scared and started to tremble, I was so anxious those days and I think It caused myself very badly when he told me that, next week he told me that, I felt depressed and my anxiety was worse, I kept having obsessive thoughts, and I felt very scared, yesterday he told me that he lied to me, but I still have those negative thoughts and now I can not believe it is a lie, and for 4 days I am having pain in the neck and that pain goes to the forehead and nose, that pain comes to me very often in the day, I can not stop thinking about this situation, why is this happening to me? Why am I still worried and scared? Sometimes I start to think that this negative thoughts will never go away and it scare me most.
