Tired

For the past two days I have been so damned tired I am at the point of falling asleep everywhere and I am really moody. Glow says I'm ovulating and well is that a symptom of ovulation? Although I can be tired to the point of passing out and still want sex. Wish my man felt the same. I'm sick of being so damned tired. I'm a CNA (Certified Nurses Aid) I feel like I can't do my job because I have brain fog and no energy.
