I've been having chest pain for the last five or so hours and finally managed to meditate and see if I could figure out what was wrong. I found out that there's some kind of dark energy in my core (I may explain more on cores later in my book 'Mythical Facts and Fiction'). I tried to get rid of it but once I finished it went right back to how it was. My brother just tried to help (he can manipulate darkness) but the pain moved to my back then, when he stopped, it went back to my chest. This energy could also explain why I've been short of breath for a while.
