Did I ruin my career?

I just told my manager about being burned out.

It was quite an awkward conversation. I could tell he wasn't very happy, but I had to be honest. Got some PTO approved for next week.

Definitely regret being honest about it a bit, instead of making something up like a family emergency. I wonder if he will fire me now..

Edit: Thank you for your support. I most likely put a big target on my back, but needed this PTO really bad
