Off kilter

Something is off with me. I feel like I've been sick for months now. I'm getting these random dizzy spells, and it's difficult to bring everything into focus. It's like being drunk without drinking. Maybe it's time to pay the doc a visit.
I pride myself on never getting sick, but last week was brutal and I barely survived with just one day off from work. Sleeping is difficult, which is an odd thing for me. I realized this because we had our company party tonight and I felt as if I was in a dream state the whole time. Everything was fuzzy, and instead of being inside myself I felt as if I was the puppeteer, pulling the strings to move my arms and legs. But to pull enough strings to get everything coordinated was too much for my head, so I'd focus on dancing around and my vision and hearing would go, but if I focused on those senses I'd have a hard time moving my body.
Actually, I know where the puppeteer analogy comes from. I was wearing a tie, or half wearing a tie, and everyone was yanking me around with it. I felt like a puppet.
Maybe I have a low red blood cell count. I'm not sure what that feels like, but I imagine it would feel like this. Maybe I just need to go out and chop some firewood or something.
