I woke up last night suddenly feeling very sick but all I can remember is having a few sips of water then falling back asleep, I then woke up this morning feeling sick but just thought it was my usual anxiety. Throughout the day I've been getting periods of feeling sick like my stomach feels heavy and achey, my mouth doesn't taste normal and I keep getting the feeling of needing to burp or hiccup or something?! It goes away slightly When I try to distract myself but I just don't understand why I have been feeling ill all day, although sometimes it's like a sensation of feeling hungry? Even though I've eaten recently and I felt okay eating my lunch but now it's just panicking me as I cannot think of anything worse than being sick, I don't know what to do, please help!
