Yes, sadness is a normal part of life and we don't want to treat sadness as a medical condition. Sometimes that sadness interferes with day to day life, and it doesn't seem to be going away. Most people who experience grief will work through it; the grief changes. So when these problems start interfering with day to day living is when people need help.

And for most people that's going to be small interventions - having a coffee with a friend who is talking to you for example. The interventions taper up as the severity of the illness increases. Talking therapies; medication; hospital in-patient stays; rarely, if someone is at risk of death or of harming other people they can be hospitalised against their will; even more rarely there's ECT.

We know that early intervention is important. And modern mental health services should be talking about "resilience" which increases someones ability to cope with daily life.
