Nothing Makes Sense lyrics

I try to be an optimist But I can’t see the sense in it When everything is going to shit Keep on smiling I wish I could give up I want to scream at the top of my lungs But I just hold it in And keep on smiling I can’t see the point Have I missed the joke? (What’s the punchline?) Nothing makes sense I want to quit I'm trying my best But nobody is perfect Nothing makes sense I am a mess I'm trying my best But nobody is perfect
