Thank you! I'm so sorry you're going through some of this too but I think you're doing well to overcome even some of it. The way I got over the derealisationwas to just stop thinking of it. I know it sounds simple and it is and it isn't but it actually worked. The more you think of it the more it feeds the anxiety and it just gets worse. It was hard at first not to think of it when I went to certain places it always happened in.
the other thing that helped was meeting a new doctor who understood. I'm not saying she ever experienced it cos I don't know, but she just seemed to get it, you know? And that helped so much cos no one I'd ever met before did. She also told me that although it's uncomfortable and unpleasant, it can't actually harm or kill you. So I just kept reminding myself of that. I literally haven't had it happen once this year, which is amazing. The thing is that even when I wasn't actually feeling unreal, I was so worried and terrified that it would start again, that I never had a moments peace in my mind.
another thing that kept me going was to focus on the times when it wasn't there and when you felt ok. I still remember one particular night, and it might sound silly, but I was say with my parents watching American idol, but it was like one night that I felt good and enjoyed myself, so I'd just think of that when it was there again and it re minded me that I can still have good times. It maybe sounds weird but it helped me.
i really feel for you and hope you get through all this too. Thank you for your reply and best of luck.
