Ok Facebook friends and fam, I've got a weird question. Has anyone else been experiencing extreme tiredness and fatigue lately?

I have been like this for a few weeks now, can't keep my eyes open and just sudden extreme fatigue and sleepiness in the middle of the day like I've been shot with a tranquilizer dart! In the middle of driving I get so tired sometimes I have to pull over and try to keep myself awake. I've been on the verge of falling asleep at work and have to try really hard to keep myself awake. I don't know what the hell was wrong with me, I even went to the doctor and had them do blood work to check my thyroids. I was thinking "damn, am I pregnant!? What the fuck!?" Today was my day off, and I slept all effing day long! I didn't get up till 3 in the afternoon and I absolutely NEVER do that! Never, I'm not talking about every once in a while, I'm talking about I never ever, ever sleep that long! I swear when I got up I was like what the hell is wrong with me why am I so freaking tiredall the time lately!? informal style garment for mother of the bride
