Can nature be a type of therapy?

One of the most infuriating things about mental illness is that there is no one cure. There's lots of things proven to make people feel better, therapy, medication, even time is sometimes a healer, but there is no one, universal cure.
I want to talk about the impact nature has had upon my mental health, and in specific, gardening. For people who don't know me, I started experiencing depression and struggling with self harm when I was 16. This snowballed somewhat for a few years and in my late teens I developed an eating disorder. Around April-May last year was when my mental health really took it's toll, I dropped out of university, was finally officially diagnosed as anorexic and my life came to a complete stop.
Through anti depressants I eventually found a little bit of solace and I started therapy.
However the thing that really made a difference to me was being outside, being around nature, and eventually when I had more strength I started gardening.
I'm not going to write about numbers or weight, because it isn't helpful to anyone, but at first I was so underweight that I didn't have the physical strength to try gardening, so I would just sit outside and look at the trees and plants.
I especially love sitting outside in the rain. There is something magical about nature because it is not man made. There is something amazing about looking at a tree and acknowledging that that tree was alive long before you were and likely will be long after you are gone. Many times when I was unwell, I would be so caught up in my own mind, my dark thoughts and my pain. I would sit outside and look after at the flowers and trees and I'd think about how these plants would be alive no matter if I wasn't.
Does that make any sense? I don't know but it makes sense in my head.
When you are mentally unwell, you lose your faith in everything.
You lose faith in yourself because your mind tells you you're worthless.
You often lose faith in services because more often than not treatment isn't available, takes so long to access or isn't what you need.
You lose faith in the world and the world becomes black.
Nature helped restore my faith in the world.
We see nature every day but do we really look at it?
When I started to look properly I saw colours I'd never seen before. I started to realise there was beauty in the world that mental illness could never destroy.
When I started gardening, I started to grow vegetables and I continued doing this through the ups and downs of recovery.
I'm no where near fully recovered now, but I'm a healthy weight and I'm able to work again, and nature played a big part in that.
On bad days I go to my allotment and look at the all the vegetables, all these vegetables that I'd grown and nurtured from tiny seeds.
It felt so good to care for something else living when caring for myself was often so difficult.
Being around nature and gardening is not a cure, but it's peaceful, it's grounding and it's reassuring that there are still pure, wholesome things in the world and you can create them.
You can plant flowers and care for them and see them bloom into beautiful things.
When your mind is screaming and racing at a thousand miles an hour, being outside surrounded by plants and trees can ground you. You finally feel able to breathe.
You see there is so much more to life than mental illness, there's so much more in this world than humans.
It's not a cure but it's a type of therapy. It's breathing space, somewhere safe.
