morning (lol, all day) sickness

I'm a first time mum. 8 weeks. I CANNOT stand for more than 20 seconds without needing to vomit. At any point during the day. I can't clean my home, showering requires me to take "breaks" as to not pass out and forget eating. I drink my meals (to stay hydrated as well as keep my calories up.). I'm averaging 800 calories a day because I cannot keep solids down and even calorie dense drinks can be a struggle. I can't go to the hospital every day for 7 months so please don't suggest I go there. I am hydrated. Just tired of the 24/7 nausea. :(

I've tried peppermints. 

I've tried dry crackers 

I've tried ginger ale

I've tried preggie pop drops

Is there ANYTHING else I can try?
