Which 5 21st century years would you not want to loop in?

2017-2022.

Some of those years were/have been decent for me personally, but the late 2010s/early 2020s would very easily be the worst era of my lifetime and it's not an era I would ever want to relive. It actually leaves me feeling bitter over the fact that i'm experiencing my early 20s during a time like this. 

The mid 2000s would probably have to be my second choice. I feel like I can't be too hard on them since they were my childhood and they make me feel nostalgic as a result, but I definitely wouldn't want to relive them as an adult.
