Exhaustion 😩

I’m an online college student and I’m trying to do homework and I can’t seem to stay awake, I slept in today, I took a nap today... I’m still so tired. I’m only 4 weeks 5days but the exhaustion is already hitting me so hard. I’m taking a prenatal multivitamin daily and trying to eat foods high in vitamins but that part is hard. I seem to either want junk food or fresh fruit and nothing in between sounds good. Fortunately, I won’t be in school for pretty much the entire 3rd trimester...but my first trimester will end the same week this school term ends so I really need to find a way to get it together...
