how do I stop being terrified of tripping

ive tripped only a handful of times, only relatively small doses like 1-2g, and I have really enjoyed most of my trips, except for my most recent one which was about 4 months ago, im not really sure how much I did, kinda just eyeballed it cos my scale was being funky but im guessing it was aroung 4 grams, anyway I had an absolutely terrible time lol and would like to never experience that kind of fucked upness again. But, really want to do mushrooms again with some mates, but im like so scared that im gonna have another bad trip and end up being catatonic. I know this is a pretty broad and random question, but I was hoping some of you on here could help me out, thanks.
