Nervous about upcoming GI surgery

we finally had an appointment with a GI surgeon who was recommended through an EDS clinic that took around 2 years of a waiting list to get into. he says that i can get a GJ tube + a G-POEM that's done with botox first before trying anything more permanent just incase it doesn't work out for me. im very nervous about surgery, but it's done in a minimally invasive way specifically endoscopic so there should be less wounds to worry about healing and hurting. i'm relieved to be able to get steady nutrition, but i am nervous about the pain and healing process and just medical anxieties in general. regular anxiety + medical PTSD has been so rough the past few years, but i am hoping this is a step forward finally at least even a baby step
