Use the noun fuddle for a confused or jumbled state. It would be easier to find your favorite shoes if your closet weren't such a fuddle of clothes, boots, and bags.
The more common befuddle comes from fuddle, which has a root meaning “worthless cloth,” and was originally defined as "work in a slovenly manner." As a verb, fuddle is used to mean "confuse or stupify." If you stay up all night studying for the math test, your lack of sleep may fuddle you so much that you can't remember all the formulas you tried to memorize!
