You are not alone!!! I have a ton of bags, lots of different brands, styles and colors. I do have occassional 'Guilt phases', but I love them all! I take care of them and use a lot of them, just not very often. For that reason, I 'try' not to buy overly trendy bags so they will be wearable for years to come. I only donate or sell a bag when I really don't like a bag anymore or my closet runs out of room (trust me i've gotten really good a sqeezing more in!). I'm lucky enough to afford the bags I have. It's really quite fun to go out somewhere and have lots of bag choices. They also always fit!
Maybe after some time passes (no rash decisions
), decide if there are a few bags you really don't like/wear any more and sell or donate those bags. That helps lessen the guilt! Just don't get rid of bags you like, occassionally wear and can afford, just because you have a lot! Think of it as a 'treasured collection'! Good Luck!
