How do people manage to not feel completely overwhelmed by life all the time?

It feels like the past decade or more of my life has been stuck on repeat—school, work, home, repeat. If I'm lucky, I get to break the cycle with a trip to the pub on the weekend. I love my friends, I enjoy the stimulation from my courses, and there are even days when work isn't so bad. But honestly, I'm just drowning in the monotony of it all. It feels like I'm trapped in a loop, living the same day over and over. Is this what the rest of my life will look like? Some version of this until the end? There has to be more to life than this, right? How do people not go completely crazy from the endless routine? My life feels like one big rut, and I have no idea how to get out of it.
