Recycle: One can buy cheap clothes, and then donate them to Goodwill. Other people will buy and enjoy the "almost new" clothes. It's a way to recycle clothes and help the community at the same time. It one wants to actually treat the Obsessive-Compulsive problem, one likely will need talk therapy and psychiatric medications. One's primary care doctor is a good place to start and get referred to psychiatry.
