Food Aversions to Everything and Nausea

I'm 7w4d. Does anyone have any tips for me? I started havin a constant battle with food. All of it tends to gross me out, and if I force feed myself something I have an aversion to, I get extremely nauseous after. The very few things I feel okay to eat are not the best for me (pizza some days, lemons another). I'm even struggling with water now. What do I do? I should mention that I have been trying the Sea band bracelets as well.
