I need support

Hi! I'm 11w6d and so far I hate being pregnant! I've been in the ER multiple times for nausea/vomiting and dehydration. First it was MS that would last all day, that subsided for a few days recently but in the last few weeks I've had really bad indigestion. I can't keep food down and if I happen to, I have this discomfort that leaves me bed ridden. I'm starving but can't handle much more than a single cracker and a sip of water. I'm breaking down almost every day because I'm constantly uncomfortable and hungry. I want to be excited about pregnancy but I didn't expect it to be this hard. I've tried every modification from eating bland to eating small meals. Doctors say there's nothing they can do. I'm just feeling defeated :(
