What to do about Morning sickness ?

I’m currently 6 weeks pregnant and I feel horrible . For the past week or so I’ve been feeling so sick everyday ,all day not only in the morning but it’s on and off throughout the day mainly when I wake up from sleeping . I haven’t even had an appetite because I constantly feel like something is just sitting in my stomach waiting to come up even when it’s empty and when I do eat something I’ll take 2 bites of my food and feel sick again . I haven’t actually puked but I have the feeling in my stomach no matter what like it wants to come up but I keep it down . What are some things I can try to help it go away ? This is my second pregnancy , I never experienced morning sickness at all with my first .
