So I'm kinda a hypochondriac and may be overthinking but I don't know. For about a week straight I've been super tired, and the past two days I've literally been drained. I'm sleeping and eating fine, and I'm not particularly stressed. I've been a bit nauseous as well but haven't thrown up. For the first half of the week I was STARVING, but now for the second half I have a decreased appetite. My body just feels weak. I was a bit dizzy yesterday as well and my head feels cloudy, I've been zoning out and staring into space like crazy which I never do. Those are really my only symptoms, no headaches, diarrhea, stomach pain, sore throat, cough, congestion, etc. There's no chance that I'm pregnant or anything. If I didn't feel so exhausted I'd be fine. Should I be worried?
