Once you accept time and space as real, you will consider yourself minute and short-lived. But are they real? Do they depend on you, or you on them? As a body, you are in space. As a mind, you are in time. But are you a mere body with a mind in it?

Your body is short of time, not you. Time and space are in the mind only. You are not bound. Just understand yourself — that itself is eternity.
