Super hungry in first trimester

I’m 7 weeks tomorrow and I feel like my stomach is ALWAYS empty. It’s worse in the morning and I literally feel like if I don’t get food in me, I’m going to just pass out lol. What makes it worse is that every time I try to eat something to help, I feel so nauseous and just sick. I can only eat like 2 bites and the food disgusts me. What sucks more is that I never know what I want. No food sounds good to me and whenever it does, it’s something that doesn’t satisfy me. Like right now, I just want pickles. 😒 I know most all of y’all pregnant ladies and ladies who have been pregnant have gone through this. Is there anything I can do to help? Like what foods I should stay away from or foods that help with nausea? I don’t know if this is a stupid question, but I’m desperate at this point.
