Feeling guilty about my collection

Some of the things I have collected are very useful in an unarguably practical sense - I can wear them, and I will need to wear them, and eventually will wear them all out. Other things were purely decorative, but made our home look nice, and my husband likes them all. But what I have felt guilty about is my purse collection. I do still hope to use them all, and use them till they need to be donated....but I did overcollect. Many have been sold (though overall at a loss). Many have been donated. The ones that remain - a huge amount - I just love too much to get rid of. But if anyone saw them, they'd think I was nuts. They all have unique colors/patterns and make me very happy. They are all very practical. But I hide them and hope no one asks why I have so many bags when I use them. They make me feel very secure in public, too, because I find they can really make me look nice with minimal effort, and people treat me with more respect when I look nice - and because I love them, they are my happy thing/friend that I have with me outside the home. I love the fact that they make me feel prepared, containing all the things I need in any situation. I love holding them, the way they feel, I love the way they look on me. Sometimes I feel caught between feeling guilty about having so many things, like I'm a terrible materialistic person vs. feeling happy and satisfied in my beautiful collection, which is complete.
