Don’t bother trying to talk with mom, LW. Make a nice bonfire, throw the clothes in it, and dance around it with wild abandon. Then roast marshmallows over it and dip them in chocolate and eat them, dripping the chocolate all over your clothes like you would have been scolded for. Let your demons fly free. Way cheaper than therapy and it should be as effective and much more fun. Do this every year with the unwanted crap she gives you until the crap no longer bothers you. Then consider giving them away instead. Best of luck.
