Nervous

Around 3 years ago I got sick. It started with kidney infections, then my kidney show signs of kidney failure and now my GI tract is now messing up bad. Tomorrow they are doing a MRI OF MY ABDOMINAL, PELVIS, AND SPINE TO MAKE SURE THERE ISN'T A PROBLEM THERE. THEN NEXT THURSDAY I'M HAVING SURGERY ON MY STOMACH. THEY BASICALLY PUT ME TO SLEEP PUT A CAMERA DOWN MY THROAT AND THEN INJECT BOTOX. IN HOPES THAT IT WILL HELP WITH MY GASTROPARESIS. EVERYTHING I END UP HEARING SCARES ME A LITTLE. ANYONE ELSE DEALING WITH ANYTHING SIMILAR?
