Living a dream with fear of the future and inevitable death

Internet has always been an interesting place, a thousand things can happen while having no impact on your life whatsoever yet it influences you and me, that's why I am writing this in the first place.
I could ask my parents, a friend, almost anyone yet I don't. It's because we're afraid they won't understand us, fear is what drives to desperate choices.
My story on the other hand is not filled with dread and hopelessness, it's mostly sunshine and lollypops with great present and the vast future of tomorrow, I have great parents who care about me, friends whom I go out with, a loving boyfriend and in my free time, I play videogames with a contrast to my happy life.
Still, as I sit alone in my room, I can't rid myself of terrible grim thoughts that there is no point in going forward, if nothing lasts forever - what's the point in going forward if you'll be the one to witness everything you've built crumble and fall. No matter if the future is good or bad, I don't want to see how all the other good things disappear from my life and get replaced.
I live in a place where time has stopped, a place where nothing ever changes and seeing how the rest of the world improves or degrades scares me, I am afraid of the fact that I don't know whether the promised "Utopia" of a country is true or not.
Fear is what drives me, fear of the fact that I am not the place I live in, time may have stopped for my land but not for me and I am slowly dying, I don't want to feel this horrible emotion.
That's why I made this thread.
