I think this song is about the point of life where, after graduating high school, there are a ton of choices and options for a person to make.
Once you are past it, you can look back at it and understand it all. After you move out, things will be better. But when you are in this situation, there are a lot of mood swings and indecision.
"I hope for you this day's coming soon" is saying that I hope you get through this period soon and realize everything.
