Recovering from depression and having a whole new life afterwards.
I can't actually remember a time when I didn't have depressive symptoms, even as a young child (had a bit of a shaky start in life). And it worsened when I was a teenager into clinical depression.
I did some reading to understand it and went to counselling and worked hard to get better, but assumed (and was told) this was it, I was a natural depressive.
Then, over time, it finally lifted, and the last decade or so has been amazing, not so much a new chapter as a new book. I'm just writing this because if anyone reading through these posts is currently suffering from depression, it feels absolutely permanent, all-consuming, there seems no way out at the time. But there can be. Don't ever, ever lose hope.
I can't give any advice - I just very half-heartedly tried everything I could (on a minimal budget) to try to fight it over many, many years - all sorts of things like doing art, trying to go for a walk, trying to keep some kind of social contact with people.
But now I've been well for over a decade, it's so clear how it's a brain malfunction, that what I thought was hopeless for so long wasn't actually hopeless, just too tricky. It was so life-changing to get better. I have gone from suicidal to being functional, and getting joy out of life again.
