I think I've become crazy

So I'm 32 weeks pregnant and this whole pregnancy I haven't had any, I guess "junk food," like pizza, burgers, pasta, Chinese food, ice cream etc. because I'm scared of it harming my baby. I even eat gluten free (also kind of did before pregnancy). Since I went through years of infertility I'm trying to do everything right but it's becoming overwhelming and stressing me out. I'm starting to feel like I may need to talk someone about my fears because I even try to balance out the vitamins I consume in a day. Am I going crazy?
