I Have Fainted Before

So with my main disability which is a pretty much being unable to feel touch or pain at all it makes it hard for my body to work out if it’s too hot or too cold.
So last year while at Disney in July it was far to hot for me. I started not feeling well and I was getting lightheaded. And told mum straight away. We quickly tried getting me to a water fountain to try cooling me off but I took about 10 steps and collapsed backwards hitting my head on a Kirb as I fell. From what mum told me I was completely out cold for about 5 mins before I woke up. A few members of staff were keeping people away to give me space and 2 were seeing to me. The first thing I actually remember was waking up in the villa the next morning. I had stitches where I had hit my head and felt properly sick that day.
