I seem to be getting hurt a lot, and I don't know why?

The last several months, I seem to be misjudging the distances of my extremities. I miss steps a lot. I trip over things that are obviously big enough to see. I get cut by objects that I have been hurt on before. I seem to misjudge the distance of doorways. I bump my head and other extremities a lot. I know I have described a clutz, but could there be something else going on??? I have never been like this before, like I said, it just seems to have started the last several months, but it seems to be getting worse.
