The accident wasn't my fault and I had very little control over the best way to navigate it.
The experience and the character of Harry Potter meant so much to me. The studio said their insurance would cover everything so I decided not to sue.
I wanted to focus on my recovery. I know so many people who don't have the luxury of an insurance policy so I would feel like a sham if I moaned about my situation.
Six years ago, I was going in for major surgery on a cyst on my spinal cord. The right-hand side of my body is getting worse, doctors can't tell me whether I will retain my speech, breathing and swallowing in the future.
The operation was a huge risk. Unfortunately it hasn't stopped things getting worse but I survived.
Before I went in, I made a short YouTube video explaining my contribution to the Harry Potter films in case I died.
I speak to Daniel [Radcliffe] all the time, we're very good friends, and he encouraged me to tell my story. We released the documentary David Holmes: The Boy Who Lived. I have never watched it but one day I won't be able to get out of bed and I will watch it then.
My acceptance of who I am has got even greater since I released it. I'm a person with a severe disability who has a platform and I push for as much awareness as possible.
People aren't aware of how difficult it is to live as a disabled person. If me and Rosie moved in together, we would lose access to a lot of our support. We live in a society where disabled people are punished to love each other.
I can't go to a cinema and sit next to her because there aren't two disabled spaces. I can't visit my friends' houses because they are not accessible. I try and shed some light on these issues. I do what I can with what I've got, I'm always pushing for more for my community.
