Feeing sick 24/7

I’m 6weeks +4 along with second pregnancy, with my first pregnancy I felt sick but not like this. I’ve not been sick but I cannot shake the sick feeling. I’m trying to eat little and often but the thought of eating makes me feel worse. I’ve completely gone of everything, like even the thought of touching or cooking raw meat turns my stomach so bad. It’s that bad that it wakes me during the night and I’m tossing and turning for a few hours. Does anyone have any tips or idea that could help me, like which foods to try or anything? Thank you in advance!
