There are two types of depression.
Exogenous/Situational/Reactive depression where the person is experiencing a stressful or unhappy life situation and are reacting as a result. They can recover if their situation improves or they receive talking therapy and lifestyle adjustments. Antidepressants will give them a boost whilst they're struggling, but they won't need them long term.
And
Endogenous/Major Depression where the person is long term depressed as a result of internal factors - genetic propensity, ND, illness, CPTSD, etc. These are the people who need treatment otherwise they can't function. Recovery is usually difficult or impossible and they may even end up needing other interventions such as ECT. If I won the lottery and could live an amazing life with no worries whatsoever, I'd still become depressed without my treatment because of my brain make up/damage and appalling past life experiences.
The people who shout against antidepressants (daily mail etc.) are ignoring the second set of people.
The first set of people can become the second set if their depression becomes prolonged or long term or goes untreated in the first instance.
When I was younger and situationally depressed, but still had the energy of youth, I doubted just how bad major depression could be. I believed that if people tried harder and did self care they could drag themselves out of the quagmire. Lol how wrong I was. I found out at 50 when I did develop major depression and I was shocked at just how bad it felt. I'd never pass judgement on those people again and I'm ashamed that I did so in the first place.
