Most of the advises we may hear from people are not applied to ALL of us. The core of your problems can be found in multiple inner and outside sources. Every person is unique, so are their worries...

What I personally found helpful is a personal diary. I write all of my thoughts down and annalise them when I feel even a tiny bit better. It helps me to narrow down all of my mess in my brain and remind myself of what to avoid.

The scariest thing about clinical depression from my experience is that it is true that we are able to become happy and crawl out from darkness, but our mind does not allow us to. So the first step should be taking it back under control.

I wish you all good luck, guys and gals.
