Hi Develyn,
Hang in there. I think I know how you are feeling because I am going through something similar, though probably you are having it worse than me. I'm also 7+weeks pregnant with twins and it hasn't been easy for me too.
I have all day sickness, have not been able to go to work for over a week because I feel so sick and weak, I walk around the house with a plastic bag for me to puke into because I just feel like throwing up so often.
And then there is the emotional bit to deal with too. One day I felt so depressed and miserable I broke down in tears. And getting depressed only got me even more depressed because I was angry with myself for being depressed and creating a negative environment for my babies.
Sometimes I also feel so useless and weak because even though I am at home whole day I can't help with household chores and can't even cook dinner for my husband because I can't prepare food without feeling like throwing up. I also feel useless because I wonder why other pregnant women are still able to work as per normal and here I am on sick leave and thinking of quiting all together because I cannot get through a day without feeling sick or vomiting and all I want to do is lie down and rest so I feel better.
So it hasn't been easy and in between the feelings of self doubt and misery I try to stay positive by reminding myself that this is all a blessing. I've been blessed with twins (and so have you) and all this is worth it.
From previous posts I can tell you are a feisty woman, way feistier than me, so I'm sure you'll get through this and will be alright
