What you say is very true because basically things when it comes to people who are addicts it is very difficult to help, because Basically what they can is money, and as for the family, that is very relative, things are only given to those families that they are united and that they are capable of helping their people without asking for anything in return, then these Types of things are what we should see, for anyone who enters into addiction there is no Reason to point them out as if they were someone bad, no , it is something that happens, just as someone can get sick, a person can suffer from addiction, but if the affected people have to take care of the possible effects that they can give to the other People who are by their side, that is something that We must all see, and be able to have the necessary understanding for all these cases, yes, the family can be of great Help, as well as friends of the Affected person.
Addiction is a sickness quite alright, and it doesn't mean the person is totally a bad person, and as you pointed out, the person needs be attended to with the same deposition as a sick person. Now the stuff its this, let's try to see it from this angle, the addicted person is sick and the people like his family receiving the effects of his addiction are sick too from their imposed suffering. In this scenario that the person to look after the sick person is sick too, now who is to look after who??, Especially when the addict isn't reciprocating the concerns and love shown to him by him family by withdrawing gradually from his bad habit.
Honestly, it is easier said then done, continuing to show support to an unrepentant person is a herculean task. Although I encourage never giving up in a loved one no matter what, but what we can't deny is the fact that the family are seriously affected in the process and only a very few will endure for a very long time.
