When I was eight, I began suffering from compulsive behaviours, feeling the need to perform tasks in even numbers.
If I didn't, I felt that someone close to me would get hurt.
The responsibility I felt for my family became really hard to deal with, but my diagnosis helped me feel like the compulsions were normal and something that I could manage.
Now, I have made a film to help people understand that OCD is something you can overcome, and isn't something to be afraid of.
