overcoming fear of jumping

hi guys ☺️ i am looking to try a waltz jump but i cant get over my fear of falling. my backwards crossovers are decent, and my backwards edges are also ok. (before you guys tell me to drill the basics first, my best friend is a coach and she thinks im ready to try this. i am always working on and improving my crossovers and edges)

i can walk through it. i can do it on the boards and off ice. but i’m way too scared to just jump on the ice!!! any advice??
