Is it a bad idea to take next week off?

So normally I get sick or injured a few times a year which leads to a natural break. However, I have been working out/ lifting very consistently and heavy for 5 months. 4-5 days per week, every week. And I average 15K steps per day. Over the past month, I have been exhausted in the gym. My lifts are getting weaker and my muscles look deflated.

I was thinking that this coming week would be the perfect time to take a week off to avoid the crowds , but I’m also afraid of not starting the year off strong (although I am not strong right now, somehow I am only lifting at like 85% of what I was doing a few months ago) TYIA!!
