"Is it possible to still be struggling with pandemic depression a year in now?"

Absolutely.

I think the longer it goes on, the harder it gets. Even though the vaccines are good news, if you are one of the people who haven't had theirs yet and are still waiting, then it seems never ending. Plus there's talk of life not getting back to normal for the foreseeable, even with the vaccination program, that we'll be stuck with masks and social distancing for a long time to come.

No wonder people are finding it difficult to keep going.
