Today (more often than not recently) I feel odd during the day. Like that feeling where you're almost catching on to something big, or you know you're just about to understand something that's been eluding you for years... I don't know if it's a vision thing, or mental thing, or what. I say vision because things look odd lately too. More "bright" or "fuzzy" depending on the moment, but both have the same feeling of impending awareness of something "more". It's a bit disturbing.
My list of possible causes isn't too long: sleep deprivation, blood pressure and/or sugar level issues, adrenal gland problems (caffeine induced), or brain tumor. I've had some issues over the last couple of years that have never truly been pinned down. The most recent round of trips to the doc during a few months of severe physical symptoms didn't end with anything conclusive, though the consensus seemed to be General Anxiety Disorder. (Since I'm online all the time, maybe it's not just GAD but eGAD? Okay that was funnier in my head.)
There are some similarities to the one panic attack I had years and years ago, but it's different enough that I'm not convinced. It's hard not to feel like there's something major, yet to be discovered, but then I feel like a hypochondriac for worrying about it.
The physical stuff isn't as bad right now as it's been, but the feeling I started this off trying to describe is unsettling. It's like getting a peek through to the other side...
