I am the same way! And my mother is too! However, this spring we rented a 20 yd dumpster and filled it to capacity (mostly stuff from the basement from when my grandparents lived here). The weight lifted was unbelievable!

I'm trying to make myself throw things away that I haven't used or worn in a year. It's hard to change your habits, but it is possible. Let me know if I can help. I make a good cheerleader. hehe
