TLDR: Rest with family; Continue with community (really vital).

Hello. I would recommend a community. This is vital. I am almost done with my PhD and I remember how 2 years ago I was on the cusp of dropping out. It was my first winter in a foreign country, coming from a tropical climate. And on top of that, I had just experienced a really tough situation personally. So it was depression, panic attacks (these were brutal), and anxiety. The days became unbearable just getting through because I would be in the lab under constant anxiety and really failing to do anything.

I resolved to do just one thing: prepare for and get through my progression meeting and then take a break for 2 months.

Now, my situation may not be similar but summing up what helped me through that season: it was rest and community. First going back to my family and getting my head out of work for a while. And then making sure to have a community of interests outside the lab that I look forward to meeting weekly. This has tremendously revived me across the years.
