Well on page 1, I gave 2 bits of advice (1 was rationalised away and the other ignored) and a personal story about how I came back from the brink of suicide (also ignored!)
Depression is weird. It feels like you are powerless sitting in a prison and a million people could tell you that you are sitting in glorious open countryside, but you can't see it. All you can see is gloom.
For me what worked is that inside I decided I had to get well, whatever it took. I couldn't continue living so miserable, and I saw the hurt I caused by trying to end it so couldn't do that again.
I took a lot of false turns along the way from (the internet didn't exist then, I wish it had) but I made it eventually step by step.
But it is weird. It feels so real. But it's not. Those thoughts aren't real at all. They just feel real. But with the right actions you can just brush them away.
