You need to maintain boundaries. Speak to someone for support if that helps. I’ve seen a counsellor due to my brother and she’s made me better at being able to say no to him. I used to get the requests for money and really worry about him and what would happen if I didn’t give him money – would he get in trouble with his dealer, etc etc, but honestly, now I know that this is not my problem. I don’t need to speak to him to see why he needs the money and listen to his sob stories. The way he is living is not normal and not acceptable and I feel that getting wrapped up in the drama of it helps legitimise the lifestyle. You need to do whatever it takes to build the strength to refuse. You cannot get into debt over this, it simply isn’t on. There are choices he could be making to get support to deal with cravings and if he is choosing not to do this then it is his problem not yours. Sorry if I sound harsh, I’ve been having this discussion with a relative and I’m sick of them getting away with treating us like cash machines
