All changes are scary but necessary in order to grow as a person. My mom is the same , she never wants to give clothes or anything away because everything has a memory to her and she gets separation anxiety so you are not alone. You are now a stronger person because you faced your fears and you gave clothes away. You are an inspiration. Always remember something that you no longer need or use its good to give it away because there are many people out there who have nothing and can really use what you just gave. I find it very rewarding to actually go to a homeless shelter or orphanage and donate clothes and canned food to the poor because they really need it. Everything that sits in your closest that you don't wear or use just remember that someone else many need it so if your not wearing it or using it it's good to give it to someone that can use or wear it.
