I had no job, no money and no family. I was young and had no identity documents, and was knocked back from government services because I couldn't prove who I was. I took the first safe shelter I could. With the benefit of many years experience, I know there were other options but at the time it seemed like the only option. There are ways of accessing help without ID, but I didn't know where to look.

It was a small, dodgy outbuilding at the back of someone's property. It was clad by nothing but tin. The wind would lift the rusty roof up and slam it down with a deafening crash for hours at a time. No insulation, no services of any kind. I slept on an old mattress, just laid on the floor. It had a slope to it and the springs were poking through. I had a single, sweat-stained blanket.

I lived there long enough to experience both an unusually cold winter and a heatwave. I remember the sound of the frozen grass crunching beneath my feet. It was the first time I'd ever experienced temperatures that low, having grown up in a hot climate.

The owner would occasionally let me use the facilities inside their house, but only ever during the day when it was unlocked. They gave me enough food to survive which they'd leave outside for me. We'd have a very brief exchange maybe once a week. Apart from that I had a total absence of social interaction. The property was isolated if you didn't have a car - which I did not.

It was a trap. It seemed better than the streets, because I had relative safety and a roof over my head. But it also left me totally unable to change the situation I was living in. I couldn't go anywhere to find help, I couldn't contact anyone. I didn't want to leave because the alternative seemed worse. I was stuck.

The owner had meant well. They had their own mental health issues and, even if they had been high-functioning, they had no idea what to do. They were a hoarder and the inside of their home was somehow filthier than my "living" space. The situation was a result of the contradictions between their heartfelt desire to help, their own anxieties and other mental demons. They were trapped too, in their own way, and had barely more contact with the outside world than me.

Isolation destroys your mind. You can't think straight, you lose your ability to solve even basic problems. You become paranoid. You hallucinate. Your memory is obliterated, not just for the period of the isolation but the memories formed before and after too. I had to piece together a time line of major events in my life from a couple of years before and after from little scraps I kept.

I lost my inner monologue during that time. The voice in your head. My thoughts became sensations and movement, like water being poured into a network of branching channels and spreading amongst them. They'd remain that for years and even more than a decade own it's still not the 'same'.

I was almost non-verbal at the end - finding even a few basic words, to say "yes" or "no" to a question was exhausting. My manner of speaking is not the same as it was and my accent isn't quite like anyone else who was born here. For at least a year later I was still losing time, hours or days, and was unsure of how I got there.

I was aware I was losing my mind throughout the process. I'd try to force structure and logic upon what I was processing but it doesn't work. The information you're receiving is already corrupted, then it gets further twisted in your mind. There is nothing more terrifying than being trapped in your own mind.

Eventually the owner, in a more lucid moment, managed to get mental health services to come out. I felt so betrayed at the time. I was terrified of them, unfamiliar faces after so much time alone. I was deeply ashamed. I'd come to realize this act saved me, but I hated the owner for it at the time.
