So many questions, so little time--wait; What?

So thats kinda how my life has been.I have so many questions in my life and I feel like its going to end tomrrow but I'm 14. 3 days ago I had a dream that I had cancer.doctors told my parents that I had 3 years to live at a maximum.But my parents never told me until 2 months till I die so i start to freak out and I make a list of all the things I wanto do-skips forward- so after I'm done in my first film and with 3 weeks left to live the doctor wants to put me on Keamo(Srry If I splld that wrong}and I told him what the point of living in a hospital for the next 3 weeks of my life in pain?He said it was for the better and I said **** off So I apply for the movie awards to host there and they except, and that is the last night Im suppose to be alive So when I arrive I have wedding dress on my hair up my husband next to me. And a tattoo that says"Im not afraid to keep on living"(big fan mcr) and I die that night I feel like I have no time. Advise?I'm worried that this could mean something
