Nope you are not alone, I collect clothing. I just forced myself to weed out two of my closets and gave 4 bags of new or like new clothing to a freecycler. I am working on my other two closets. After that I am going for the basement, which is a disaster as I have so much stuff stashed in there that I can't walk into one section of it.
Like I said you are not alone.
