Idk what to do help!

So I’m 6w5d & I’m having nausea all day everyday and get worse and worse each day. I can’t eat cuz if I do I get sick if I don’t eat I get sick if I get small or big meals I get sick. I see food or smell food I get sick. Idk what to do & im starting to get cramps all over my stomach & at times hurts to move. Could it be cuz I’m not eating enough? Idk what to do with the eating thing cuz it like I’m set up for failure no whatever what I do. Also I been feel weak and dizzy I’m sure cuz I can’t really eat. Any advice
