There's something missing in my life¿
Но это глобально)

+++Tatiana

Очень размытый смысл. Есть мноlго вариантов. I’m short of something. Или I’m in need of something

I'm just not sure whether they're complaining about their life or just could do with a cold drink, for example. There's context missing.))

I think your translation is perfect since it's more general.

If it’s just a general lack (with no specificity as to WHAT is missing and WHERE (in one’s life, etc.), then I think “I’m missing something” is general enough, and still natural as a standalone statement.

hahaha, we wrote that at the same time)))
