I dont Know what to do ?

Im 13 weeks and 6 days pregnant with my second but this pregnancy is so different, with my 1st I didnt have any symtoms but with this I have everything possible on the pregnancy list lol... I feel like eat good but I always end up vomiting or with nausea, and everytime a family memeber havent seen me in a while they tell me how skinny I look, Im losing weight and its driving nuts and om gettin really depressed about it.
