i get depressed easiliy

Since i was a small child i imagined i would be rich,famous,my life would be excellent ,like a movie.When i grew up and people started saying you probably won't be the president of USA,you won't be rich,you won't meet Batman,you aren't the smartest man in the world.I know this thing are reality,but they depress me,make me feel miserable,make me feel worthless.I tend to be idealistic because i feel depressed when i meet reality.I know what its real,but it depresses me,makes me feel useless,like my dreams are dead.How can i just look at the real world without  feeling depressed and feel like crying?i don't cry,i just feel like a kid wich their parents bring him instead of his favorite toy(wich probably is ideal)something very simple for hist birthday.
Can medicine treat this kind of issue?

I can only give you the same answer that I did for your last question. When you say you are disappointed because your wish to live outside of  reality is not being granted, then you have some good hard thinking work to do, and can probably only do that work in therapy.
