Do I die in my sleep everyday?

I've been having bad anxiety attacks, and I know derealization is a symptom. Right now things feel real, but I keep asking myself the same questions things like "am I in a coma" or "is everyone just acting". I got over those questions by simple logic. However I have now posed myself with a question that cannot be answered. What If my conscious dies every time I sleep and a perfect replica replaces it. Apparently this is a question that has been discussed by people before. My logic behind it is this, when we sleep our current conscious passes on our dreams our just an afterlife for that consciousness, while we are sleeping a new consciousness is made complete with memories of everything that has passed including the part of our former consciousness departing. Perhaps this is why we can't go too long without sleep, and why we don't know why we dream. Our consciousness was not meant to be alive for too long. This process happens until our physical bodies can no longer support us, and when we lose our minds it's because the process malfunctioned and now it is replicating a flawed conscious. Is the me of today the me of yesterday? Will the me of tomorrow be the me of today? Would I even be able to tell, if my conscious was perfectly replicated is it the same? I read that if you question if you have a distorted reality then you don't have a disorder, because people with disorders don't realize their reality is distorted. But now I can't move past this because there is just no real way to know, I am coming to terms with this thought. If my dreams are my afterlife then at least I got one, and the "clone" will carry on what I wanted before just like I would. In my mind right now I'm conflicted on whether or not to accept this as my reality, what do you all think I should do if I should even do anything?
