Replying to Any tips on first flip?

Hey so I've been skiing in the park for two seasons now and I've been skiiing pretty much all my life (started at 3). I am pretty comfortable on rail since I can do spin on/off and swap but when it comes to jump I'm just so scared. For some reason whenever I want to do something higher than a 540 I get scared and pussy out but this year I want to throw some flips (probably flat 3s, 5s) or maybe a switch cork 5. Last year I trained for maybe 5 months before the season on trampoline and was pretty much able to do any flip variation up to 900 and double corks / double flats. But wasn't able to throw anything big. What can I do to really feel ready to throw my first flip on snow?
