You don't. A succinct lyric that helped me eliminate the stigma in my mind around not "being into it" all the time:

> It's oh so sad to be happy all the time.

Society, in general, is a mirage. Most people are insane and insanity is contagious. After 2.5 years of non-stop insanity and some variant of psychological abuse, it's not only okay to feel how you do, but should be expected.

A short read that helped me to realize and accept this is Awareness by Anthony DeMello [1]

FWIW: Don't let the world get you down. Look at your desire to consume content as a phase that needs to pass like a thunderstorm and enjoy the rain.

Think some people here can benefit from reading these two:

Why? They help to rewire your brain and help you detach from a lot of the things and ideas. Not a silver bullet (depression is one of several, natural, human states) but may help some who want to avoid the pharmacological route.

My favorite introspective book is Awareness, By Anthony DeMello[1]

It is a small book but it really makes you think about your views on life.
