How do I get over my fear of jumping?

Accept your fear and let it be there. That might sound a little strange, but we often try to "get rid of" fear because we believe we cannot do what we want to do while we are afraid. We can! You can challenge yourself bit by bit, in spite of the fear. That builds positive experiences in the right direction, which loosens the grip the fear has on you, and the feeling starts to matter less. In time you will barely notice it, and for some riders it disappears altogether. It usually takes a little time though 💫
