What's Wrong With Me? Exhaustion and Unusual Symptoms

I’ve been feeling more exhausted when I get home lately. I’ve never needed a nap ever, but now I’m taking little naps when I get home and I’m still super tired so I go to bed at like 8:30 and fall asleep super quick. I usually go to bed and lay on my phone or read for a while but not this week. This isn’t like me at all. Idk what’s causing this much exhaustion. I do work with kids but I feel like I would be this exhausted everyday after work but I’m not. I’m just feeling super odd latley (only when I get off tho) today, I’m cold but my skin is hot (no fever) and no appetite. What’s wrong with meee? I just wanna feel normal again.
