You have 2 weeks until payday, what things can you put in place before then? I know you said your mum couldn’t hold your money but how about your boyfriend? If he isn’t actually holding it he could still help you be accountable for how you spend it.
Maybe you could find the courage to tell him? He will be better placed to help and support your recovery when he knows about the problem. You won’t just be presenting him with a problem; you will be showing him what you are going to do about it.
