Thanks for this write-up! This is actually a long-term follow-up: one year between each episode! Your readers may need to be patient... ;) I actually vaguely remember having read something about depression connected to inflammations, but I was not remembering well. I am happy with the summary in the post. This seems to make sense (actually the entire post was quite comprehensive, as said by @abigail-dantes), at least for the non-specialist who I am.

Instead of asking questions (as I think I have mostly followed everything), there are two items in the post that made me laughing and that I want to emphasize here.

Think about it this way - while you wallow in your sadness for years, not having any interest in sex, the other members of your species would simply outnumber you

This sounds weird to my ears: “please don’t be depressed or you won’t transmit your genes”

On different grounds, I have learned that anhedonia was a word today… :D
