Not to speak for Laura or anyone else for that matter.
Though your sentiment is nice, that's not what depression is. In reality, there's still lots of research to be done into it. It's a very complex condition since it involves our most important organ, our brain.
Currently we use drugs to help. There's some scepticism of whether these actually work or are good. At this stage, the consensus is that it's 'better than nothing' as they are shown to help. The bad part of these drugs tend to be the side effects.
Unfortunately these drugs are being dished out far too easily (most professionals agree with this) and I highly disagree with that. Everyone has bad times, that's part of life, using drugs doesn't solve the problem.
For some people however, these drugs can be a life saver and life changer. I don't believe though that they should be a long term solution and counselling should be part of the package.
Seeking help is usually the first step to recovery. Sometimes even realising you need help is the hard part.
Depression is a mental condition that can have serious consequences which can lead to physical harm if not treated. It's more than just about the past, the present or the future. It's a combination of things that we simply don't understand. As we simply don't know why someone feels like they do. What causes it and what to do exactly to fix it. That's the simple reality. We have 'ideas' that work but it's not perfect. Each person's situation and condition is unique. There is no simple solution.
That's where we are with mental health. We're still at early stages because it's one of those things that doesn't get discussed enough. That's not to say it's all bad, it's actually good that we have solutions that work. Just need to be better.
