welcome to S.R. you are so right, you deserve a life.you do not own your brother anything. it is his problem. you can not keep him clean & u can not make him use. your parents are enabling him & you are smart to back away. he needs to hit his bottom before he will be able to get clean.as long as he has some one to pick up the pieces the longer it will take for him to realize he has a problem. i am sorry u are going thru all of this.read around & keep coming back. do not feel guilty. prayers,
