A little background.

I have pcos with insulin resistance and other issues; one is a mass on my left adrenal gland. We've known about this mass for 2 1/2 and it's been a long fight; just one test after another after another after another. I've done the testing the endocrinologist wanted. Now she tells me I have high aldosterone, which we knew a long time ago, and wants me to do a surgical procedure called Adrenal Vein Sampling; it's scheduled for mid May. It's kinda like when a heart stent is put in; the doctor sticks a tube in a crotch vein, goes all the way to the adrenal gland, grabs some tissue, pulls everything out, and does the other side. Then you have to lay still while the doctor and the lab make sure the samples are good; if they're not the procedure is done all over again. Depending on the results of the tissue analysis, removal of the mass and/or adrenal gland(s) is next. This is an all day affair, I can't eat after midnight the night before, the instructions say to take my meds but I can't because they have to be taken with food which means I'll miss several doses of meds, my stomach is gonna be all messed up from missing meds and possibly send me to the ER, and I don't know if there's any sedation. I'M FUCKING TERRIFIED AND FREAKING THE FUCK OUT. I have severe anxiety with panic attacks and ptsd. After I got off the phone with the scheduler yesterday I immediately threw up and have been in panic mode since. I thought if I did some research and watched a few videos about the surgery it would calm me a little. Nope just made my anxiety worse. The last procedure where I couldn't eat for 8-12 hours landed me in the ER due to the stomach pains and nausea from missing 2 doses of meds. They're gonna have to knock me out for this and send me home with painkillers and nausea meds. I'm so scared and I don't want to do this. The only people that know about this are the doctors, my husband, and my best friend who's like a sister. I haven't told anyone in my family because they have some medical stuff going on and they live awhile away from me so I don't want to worry them. I haven't told anyone in my husband's family because, well it's easier to say I've had a huge falling out with them; they probably don't give a damn anyway especially since all of my husband's siblings are expecting and we never will have kids. I'm so scared and really don't want to do this!!!!

Has anyone had this adrenal vein sampling done? Oh I'm so terrified....excuse me while I stick my head in the toilet.
