Ok explain this to me because I’m tired of google!

Ok so I’m at 8weeks and few days. When I think of house food I get disgusted. When I order what I want I barely finish it and get this disgusting feeling after then it goes away so I eat it again then again it repeats. I’m laying down and not feeling so well at all. Yesterday I went to the supermarket to get cookie dough. And guess what the supermarket is just downstairs across the street. I got sooooo dizzy and had cramps while waiting in line and then started sweating like crazy. I went upstairs 4th floor no elevator to my apartment. Sweating from my upper lip and everything. Ran to my room and threw myself on top of my bed with the AC on. I have never felt that badddd I felt soooo weird. Cramps , nauseous, sweating. Was I dehydrated? Idk. But is all this normal !? Is it morning sickness? Is this how it feels since I never had any symptoms. Now I’m just disgusted with everything ugh even water.
