I don't know: I don't know, john.  Technically, every person who is alive will die someday, yes.  But unless you have been diagnosed with some untreatable illness, then no, you are not actively dying.
If this is something you worry about a lot, mention it to one of your parents, a close adult friend, or a school counselor.  A lot of people have these kinds of worries and you can get help to not worry so much.
