Depressed: REALLY BAD NAUSEA

I am 8 weeks pregnant tomorrow, this is my 2nd pregnancy but first child. I never experienced Nausea my forst pregnancy as I had only moscarried at 6 weeks from my 9 week u/s. Anyways, these last 3 days every single day Ive had no appetite, eat really light n feel "full", the look at food makes me sick. Idk what to do and Im crying because I really want to not be pregnant anymore because i feel so miserable and this is not to offend anyone but I am really just upset and ive tried saltine crackers, ginger ale, nothing works. I have Diclegis and it works sometimes but not fully. IDK what else to do. 😭
