Currently my mind is clouded with thoughts of college, money, friends, intellectual subjects, deep thoughts, emotions, too many things on my mind is making my life messy and unorganized.

My Curiosity has taken over my mind and I cant stop learning, cant stop exploring, cant stop thinking. With this new knowledge has its consequences and some days I'll feel depressed and hopeless as I learn more and more. As I learn more I discover even more opportunities and realize that one could never know/understand everything. This keeps me distracted most of the time from my priorities in my life as I want to experience as much as I possibly could within my time on Earth. Could too much knowledge lead to unhappiness? Has anyone ever felt like this and if so how do you deal with it? Is it bad to try to understand everything?
