Somatization Disorder?

I’m getting confused. I was in the hospital from Sept 28-Nov 18 for GP. My GES study shows severe GP, after 4 hours, only 12% of my stomach contents have emptied. Thats a huge delay. I was formally diagnosed w GP months ago. Ive tried reglan, haldol, zyprex, zofran, erythromycin, azithromycin, compazine, amitryptaline, etc. I’ve been on IV antibiotics and zofran this whole time and still am going to an infusion center to get those and fluids. I have a PICC I am having my pacemaker consult all the way in Philly in 3 weeks and vomit 12-20 times a day. I keep reading my doctors summaries in my chart and they keep mentioning “somatization disorder”. I KNOW that the brain and gut connect is real however, I personally do not have any troubles mentally. I am not anxious, I sleep well, I have a clear mental state. The doctor keeps saying to not be offended by the term somatization disorder but I can help but feel undermined. GP is terrible, I don’t like feeling as if it’s “anxiety” and a matter that I need psychiatric help for. Can anyone else relate? Any advice? Clearly I am not being understood too well.
