This happened to me 10 years ago, I got sick and fought for my life for around 30 days, and after healing I started having side effects - after effects of that illness and I literally couldn’t do anything for like 50 days. I literally haven’t felt depressed at all before that but since then I have depression and some episodes occasionally especially night time before I go to sleep.
I really wonder if anyone experiences the same thing.
Depressive episodes go up for me any time after a long break from ordinary life (including vacation, even). For me, so much about depression revolves around being unable to summon the motivation to do anything, which causes further depressed thoughts, which further depresses motivation. Breaking out of that loop is hard, and it takes time to get back in a routine that supports good mental health. I guess what I’m saying is that “momentum” matters for doing things; if I’ve been doing things, it’s easier for me to do more things.
As far as things peaking in the evening, that’s a classic. My spouse calls it my “10 pm ruminations” where I’ll find myself staring at the wall for a while then say something like “maybe I should [action that would completely change the direction of my entire life]”. I don’t know if that’s depression necessarily, just ordinary human existential angst.
I’m sorry that happened to you. I haven’t heard about anyone experiencing this but it makes sense that life altering events can permanently change your brain chemistry.
For me the exact opposite happened after I got a bad case of a nasty variant of covid (first time I got it at all) where my depression just completely disappeared when I recovered
I’ve experienced a sharp increase in my depression after going through many surgeries in a row. Being previously depressed, all that time bedridden wasn’t good for my mind.
If you are asking if some infections can induce chronic depression then I can’t say much.
