Eli5: what makes us sleep more when depressed?
gpt
I'd like to point out that depression affects different people differently. It might make some people sleep more, and it might make some people have a very difficult time sleeping. It might make some people overeat and some people _stop_ eating. 

It's basically not very well understood, to be honest. We do know it makes just about everything more difficult, more stressful, and makes it so a person is pretty much unable to experience joy. But how that manifests, that's very individual.
