Morning Sickness/All day everyday

Sabrina
I'm just past 12 weeks and the doctor said that I would start feeling better and if it's possible I am feeling worse, the morning sickness/all day and the headaches keep me in bed most days which is really hard when we have two daughters already and my husband works away... I can barely shower myself or get groceries without fainting or being sick! Someone please tell me there's an answer or something that will help!! I want my energy and life back!! 
(I also am on dicletin which does not seem to help at all)
