I went through a similar thing earlier this year. I wasn't riding up to my normal standard and it was very frustrating. Every time I rode I tried harder and harder to get back to my normal self and that ended up just making things worse. I went to a sports psychologist and he told me to just go and do what I know best! At the end of the day nothing else matters during the two minutes you are in the ring. I just took a deep breath before I went in and tried to not think about any pressure or worries. It took me about 2 good rounds and then I was back to my normal self. Don't worry too much about rough patches. Everyone has them!
