I wouldn't described life as being "trapped". I'd actually say it's quite the opposite. It's easy to feel trapped when you're in your house, working on papers/homework, deadlines approaching. But have you ever realized how limitless our lives are? I'm actually plagued by the thoughts of the opposite nature to what you feel. Sometimes I fear that my life will be too short for me to fully enjoy the many things I dream of. Just take a minute and think of all the people you can meet, potential soulmates and best friends. All the languages you can learn, all the funny reddit posts you can read. Life is like a video games with so many choices and variables, there are and infinite amounts of endings. You should take a walk and enjoy nature. If you live in the city, just watch all the people walk by, living lives of their own. It's quite interesting to think of all the things that you will experience, and unfortunately never experience.
