Damned if I do and if I don't! HELP!!

I almost always feel sick and gross every day.. However it's the mornings and nights that are THE WORST! At night I usually feel like I've been punched in the stomach really hard and I'm starving, however if I eat something it just sits in my stomach all night and I wake up super early feeling nauseous... If I don't eat anything I'm stuck lying awake until the pain and hunger pass and then I begin to feel a little nauseous anyways especially in the morning on a super empty stomach. Honestly I can't do this anymore I'm done feeling like this. Help!!
