Hello, this all sounds very similar to my son who is/was taking cocaine. When he had his kids I would buy food for them. I ended up buying all their Christmas presents and food a couple of years ago. Eventually he kept putting me off going to his house, he stopped giving me his washing and borrowing my Hoover. When I got to see the house it was an absolute mess and took weeks to clean before it was eventually sold. All that you have said about your daughter is just like my son – blocked nose, sniffing, mood swings etc. I would suggest trying to speak to your daughter whilst it Is still early days and before she gets in too deep. If she loves her kids maybe focus on how her behaviour is affecting her kids. My son has had periods where he hasn’t seen his kids for months at a time (they live with their mums). It’s difficult as we tried to support our son through a drug counselling service but he stopped going and now I haven’t seen him since November but my husband manages to text him and get a reply.
Danman is right though unless your daughter wants to stop there is nothing you can do. That’s why I thought if you can focus on her kids it may make her think about it more. We have tried everything with our son and have always been there for him but he has literally cut us off and we don’t know what he is up to. We went to counselling ourselves when he was staying with us which may help you get some support, again through the local NHS addiction and counselling service. Any more questions just ask.
