Does anyone else feel ‘reset’ after they recover from sickness?

I just got over a nasty cold that lasted a week (sore throat, cough, plugged sinuses, etc). I just recovered and honestly feel like my body reset. I am an extremely anxious person and am susceptible to periods of depression. Ever since I recovered, I have not felt any anxiety, low moods or the usual feeling of dread and gloom I carry. It’s weird to say, but I feel like the world feels like it did when I was a kid. I can’t really describe it, it’s hard to put into words, but I feel really at peace. Anyone else ever felt this?
