Oh I wish I could clear my closet out but I just can't part with these things.
I felt the same way as you, but what's the point of keeping things you don't use and having it take up space? Do you use everything in your closet? 
I don't use it but I've collected so many little things in memory boxes. It's really grown to a few boxes now. 
So the items are sentimental to you? I know how hard it is to part with items that have memories behind them, but at the end of the day, they are just items! :)
They really are. Maybe I should put them into a scrapbook!
