My opinion, having been on both sides of the coin, is that getting upset is the very last thing you should do, as har as it is. I looked for the middle ground and began speaking calmly about how life could be easier for them if they organized these things and were prepared. I would always say that they could chat with me about whatever’s on their mind, so that if mum or just themselves weren’t doing what they should, I gave myself the best chance of being able to help. When I got upset, it was essentially cutting off any chance of being someone they could come to for help. Hope this helps, mate, and good luck 🤜🤛
