What would it feel like to be level drained in real life?

What would it feel like to be level drained in real life(Dungeons and Dragons)? I want to compare notes from a bad time in my life.(ex-girlfriends ect.) I felt like I was being level drained and I became 100 lbs underweight and I failed out of a crappy university… and I wondered is this what it feels like to be level drained? Having ones soul devoured? Emotional pain overwhelming…. the urge to give up… and stop stuggling… fear and anxiety?
