Pregnant and no longer smoking weed

Although idk how true it is that marijuana affects your baby ive been trying to stop so far So good but the main reason I smoked is because I have anxiety and the medication didn’t react well with me . Ever since I stopped smoking I can’t eat I’ve been losing weight when I should be gaining and I wake up out of my sleep having panic attacks I’ve never experienced this and idk what to do im only 6 weeks so I have 2 more weeks until I can see a doctor.
