I try not to care...but he needs help

So after my relapse a little over a month ago my uncle left the home and went on a major Meth binge lasting about 5 week's, he returned 2 day's ago,lost approximately 20lbs,covered in dirt a filth,hadn't showered once the entire time and his mind was slipping but being awake for 5 week's will do that.The ground rules were laid out again."No Dope Allowed PERIOD In Our Home"and I could see the depression and worthlessness he felt on his face,I am unable to hate or not help even after what I've been through with him so I got him some clean clothes,told him to shower,made him a place to sleep,and have been making sure he eats 3-4 time's a day and after he just sleeps and probably will for 7-10 day's. I try not to care,I try not to let it eat at me...but it does so again he gets another chance to recover but this time will be a little different as his probation officer is on him about having to much spare time and now that she is hip to what's going on he has no choice but to get his sh*t together or go back to jail so he gets another chance with me and my family however if he goes back to the dope now he goes back to jail so I hope this will help him stay on track this time as I only want the best for him but at the same time he must help himself.Caring is tough

Thank You for the kind word's and unfortunately I found chunks of crystal meth on the bathroom counter yesterday where my family brushes their teeth,I scrapped it up and cleaned the counter and showed it to my mom so that she could see I wasn't luring and I left with my brother so my mom could talk to him one on one about the danger he put the entire family in especially my 7 year old sister as she could have accidentally got it on her hand and kids are always putting their fingers in or around their mouths so anyways as my mom was trying to talk to him he didn't apologize or anything he just grabbed his key's and walked out the door.Today I am folding up all his blankets and moving all his thing's to one section of the home and as of now both myself and my mom are just waiting for him to be violated by his PO as he told my mom he has multiple dirty drug test so now he is gone and my family has to wait for the Sheriff's to come search our home for him.Its hard to care for a person who doesn't care about us
