ELI5: Why do so many drugs cause suicidal thoughts?
gpt
Most anti-depressants (and similar drugs, like sleep aids) work like this: they make you motivated to do things. Whereas before you didn't feel like getting out of bed, now your brain is stimualted enough to want to get out of bed. Before you didn't want to fix dinner, but now the drugs are telling your brain to be really, really excited about cooking dinner.

Unfortunately, these types of drugs encourage you to be motivated to do *everything*--including, uh, suicide. So the same drugs that are motivating you get get up, go to work, and interacting with people is also motivating you to commit suicide.
