Well this is very important topic to discuss and share idea.

I have gone through this process as one of my best was suffering from toxic.Due excess use of toxic his attitude towards became rude and he faces problems like short,temper,short memory lost etc.

Similarly his family members were in tension due to his behaviour.few days they show alot of patience towards their child but due to my continous poor attitude they became alergic and left their child alone.

But being a friend i grab his hand starts to know the facts due to which he develop toxic habit.and then slowly and gradually i tried to meet the people who assists in solving my friend problems.
After few weeks i succeeded in solving the problems of my friend and then i hospitalize my friend in a well know hospital for his best cure but i met him regularly in hospital and talked to him and his family to show flexibility in manners so at last my friend recovers from toxic now he is happy and healthy.

So never left such patient alone
