The healthcare system prescribes these things as a cure. They are not. The meds have a role to play: they can give a person a lift, and time to address the depression. They can learn coping skills and lifestyle changes while on an SSRI. The idea that a pill solves the whole thing for life is ridiculous and dangerous.
Some people take ADs believing there is a quick fix pill for their depression.
They aren’t - they’re simply a tool to help you manage the symptoms while you work to address what is really making you depressed in the first place.
Depression isn’t completely caused by a chemical imbalance in the body and there are lots of reasons why people have a hard time overcoming it.
