Does your POTS give you terrible IBS/IBD symptoms?

I tick pretty much all the boxes for POTS. I’ve read it can mess with your stomach and mine has become so debilitating since I got covid back in June that I can barely get in the car or leave the house. I know my anxiety plays a big part in that but I never used to be this way. I’m 23 and I barely have a life. I don’t know what to do anymore. Even trying to go to my doctors ( 10 min drive) is too much for me but it’s gotten to the point where he’s said he’s at a loss with me because anything he’s put me on doesn’t work ( example: antidepressants but did a blood test to see if any work well with my genes and none do, pain killers etc )

I honestly feel like I’m going crazy. I’m down to 49kgs and I can’t seem to put on anymore weight. They put me on a Low FODMAP diet after I had to stay at the hospital for a week after I had starvation ketoacidosis because I couldn’t eat a single thing anymore without reacting badly. I got down to 43kgs and for context I’m a 5’2” female. I know this might not belong in this group but I’m honestly begging for help at this point. Unfortunately I’m in Perth Western Australia so any Americans that read this and suggest clinics or similar things, I appreciate you but can’t fly to America for help if I can’t even leave my driveway 😂☹️
