Everything feels weird

Ok, so ever since halfway through November (from the 17th to be exact) Ive been going through what seem's like hell, it started off where any kind of movement would feel odd and unnatural to me, sparking questioning and worry, then it became any kind of sound feels weird too, and since then it's like if I focus on something in a negative way for a tad too long without changing my attention it'll stick to me and haunt me for days (or weeks) on end. And the only way I seem to shake it off is by my attention changing to a different problem (and if that one goes away, the older ones come back, you get the idea).

And it seem's so completely random, like a few days ago it was laughing didnt seem right, and today just the sensation of my arms feels weird and unnatural to me, how bizzare is that? >_<
