When it comes to anything depression related, you should never rely on anecdotes alone.
The world is a big place. Many people have tried depression treatments. You can always find someone who had a very negative experience with something.
For a counter-anecdote: I know someone whose mother was deeply suicidal and unable to function for years. Eventually they tried ECT and it was the turning point in her depression. This was decades ago and she’s still doing okay today.
Do not let internet anecdotes steer depression treatment. ECT is an extreme example. I’ve seen countless people who avoided any depression medications for years because the internet told them SSRIs were evil drugs, only to experience life changing results for the better when they finally listened to their doctor and accepted treatment.
