Sorry, I wasn't able to reply. I was out of city on holiday and didn't have access to the internet. I appreciate all the replies. You gave me strenght to do the right thing.
My father didn't call me whole week because he knew i was away. He will probably call me or show up at my work tomorrow and ask for more money. I don't want to turn him down completely if he really neeRAB meRAB so i will just tell him to give me his prescription and i will get it for him and send to his home address by courier. If he says it is for the hospital, i will tell him to make his brother call me and tell me it is for the hospital personally. Even if he does this, i will not be handing the money to my father, i will give it to his brother because he's the one handling all finances related to his treatment. If he doesn't accept this either and try to find excuses, i will tell him that i'm not stupid and i know he's been drinking and i'm not giving him anymore money. I will also tell him to stop showing up at my work without calling first. I will try to be as nice as possible but this has to be done. If my uncle (from my mom's side) wants to give him money for alcohol, he should do it himself. I don't want to be a part of this anymore.
