Is everything gonna be alright?

"All I know of life is pain [b/c] everyone who lives is also dreaming" (Life is a Dream by Calderon)
I do not know if I completely agree with the quote above but at least, I know that dreams don't come true in real life. One minute before, I felt like I was the most lucky person in the world since I had everything I am wishing for now: popularity, family, happiness, friendship, confidence, independence, and a belief in myself. One minute later, everything mysteriously evaporates, and I feel like I'm such a failure, a big fat loser! If life really is a dream, then mine is a nightmare right now. In this dream, I'm scared, lost, frustrated, painful, and confused.
Everything is for nothing. All of my hard work, all of my determination, all of my effort are for nothing. Since I was in kindergarten, I have been working so hard to touch that dream of mine. But now, I suddenly realize that dreams are only dreams; they will never come true no matter how much effort we put into them.
If "life is a sweet lie" as Calderon has said, then I would never want to wake up. I have lived in that dream, that sweet lie for so long. I've done everything I possibly could to reach that goal and I even believed that it was possible to make dreams come true. However, at this moment, I am awake and recognizing that all I've always believed is simply a "sweet lie." Reality is the opposite: painful, disappointing, discouraging, and hopeless.
I keep asking myself if everything is gonna be alright. I wish it could but something inside me is telling me it cannot be alright. I'm haunted by the past, disappointed at the present, and afraid of the future. How can a person with no hope in the past, present, and future be alright? One part of myself is trying to convince me that everything is gonna be alright; it keeps encouraging me that as long as I do not give up, miracle will happen. In contrast, the other part of myself is saying that I should not believe in anything in this world. It is bad enough to be hopeless; it is even worse to possess a hope and then lose it to life. There is nothing in this world can be worse than giving someone a hope and simply throwing it away. I want to give myself a hope in the future but I'm also afraid that I will hurt myself again. Without hope, how can person survive? If they can, they are simply a body without a heart. Will I be that person? Will I be the person with a concrete body but no soul?
