Is there rehab for shopping addicts/hoarders i am 16 yrs old?

Yes : Any habit/vice/ritualistic activity/thought process that impairs you from doing normal daily activities needs to be adressed. By normal activities I mean going to school , studying, going to work, cooking , having friendships , going on vacations, driving and so forth . If this is happening to you a clinical psychologist can help you . That would be a good start
