This isn’t an accurate description of the possible side-effects. Anti-depressants can cause meaningful side-effects including changes to appetite, difficulty regulating body temperature, nausea, changes to sleep, and akathisia. They are also very, very not fun to quit abruptly if you run into an intolerable side-effect. That said, nothing that you said about depression is wrong and the effects of untreated depression can be far worse than the side-effects of anti-depressants. It can just be hard for people to tell what is normal and what is abnormal and potentially caused by their medication, so they should be informed so that they can switch medication if they run into side-effects. (And know if their doctor is not providing them with good information.)
