Hi guys I am new to this site and new to riding in general, I wanted to ask about an experience I am currently going through that I'm having difficulties with, I recently did my CBT with a group of others and completed the course, now I have my own ride and gear and I'm raring to go, but tonight when I got on my bike I suddenly ended up panicking, almost a fight or flight response and so I ended up not going anywhere. It doesn't help that I keep being told to be careful before every attempt to ride as I'm finding that puts my mind in a state of awareness of everything around me all of a sudden. I've had my bike now for nearly a month and unfortunately due to the weather haven't been able to ride. Has anyone else had this kind of experience? I'm trying to fight through the fear and tell myself to just ride the bike but I don't know if this is a normal experience to have or not.
