Lightheaded/dizzy 30 weeks

Dont mean to sound like I'm complaining because I am extremely grateful baby is growing well and I'm blessed to be able to carry and baby but man am I so sick of feeling sick, dizzy and or lightheaded when I dont eat or just because, the aches and pains of what feels like bones are breaking. I just want to feel a bit normal again. Anyone in the same boat with these symptoms. I'm going crazy over here.
