Hello, I am 9 weeks pregnant now. I feel so tired and drained this past few weeks.

I’m suffering from severe vomiting and I can’t sleep. I spit 24/7 because of too much saliva.. I lost almost 5kilos now because of non stop vomiting.. Everything is hard, breathing, eating. My stomach can’t even accept water. I cannot take my vitamins because of this feeling.. I feel so weak and hopeless and I need your advice.. please help what can I do? What month do you feel fine?
