Thanks everyone for your replies. As I suspected, after his initial reaction, he did come down a good while later and offer me a cup of tea (major event!!)
He did then actually initiate a talk about diabetes - the first one we have had in an age, and all calm too - major step forward! (Could this have anything to do with the fact he had had a dose of Humilin S before dinner and had better levels that he had had in a while???)
At the moment he is still staying he is not going to clinic next Monday "as they will force me to stay in and I am not going to!" I have said that everyone only has his best interests at heart. They are only trying to help him. He said that with exams coming up there is no way he is staying there, "If they want me to go in the summer holidays, fine, but not now!" I did then go on to say that if he does start doing exactly as they ask, and have figures in his meter to prove it, that I am sure they will be fine to let him come home again on Monday.
I did say to him that almost certainly the first few readings will be high, but if he does stick rigidly to his regime he will see the numbers start to fall, and that half the point of testing is to see if the dosage is right and if it's not it can be tweaked. He admitted that's half the reason he doesn't want to test at the moment because he knows it will be too high. I said again, if they can see the readings are coming the right way, it will give them a much clearer picture than just having one or two readings. I will definitely ask the DSN to contact us again at the end of the week, actually maybe on Wednesday too, to speak to him directly, so she can ask him what his levels are doing and suggest alterations to his doses if necessary. As I have said before, we have NEVER been given told how to calculate correction doses, so have never done that, but given that he is now on Humilin M3 and Humilin S as well as Lantus, he is just on fixed doses. We have never been told to restrict his carbs either though, so he eats whatever our main meal is and whatever else he can get his hands on and still takes the same amount. I don't even know if these other insulins are like Novorapid in that 1u equals x amount of carbs (10g in his case on Novorapid).
He did stay downstairs fairly late with me last night, he actually asked me to say down with him when his dad went to bed, something he hasn't done in an age so I think he is feeling quite vulnerable at the moment and is maybe backing down a little. I really did emphasise that both me and his dad and his team are only looking after his best interests. I told him all the soppy stuff that's its only because I love him that I want the very best for him, that I want him to remain well and complication free and that it really is possible to do with a little work and commitment from him. He did say for not the first time (and I totally understand his need to) that I can't possibly have a clue what it means to live with diabetes day after day, that there is no let up from it, and all I could do was sympathise and agree and say that it is a load of cr*p but he has no choice but to accept it and make the best of it. I quoted the 'you control it, don't let it control you'.
I am now going to be walking a bit of a tightrope this next week. I had agreed a while ago to completely back off and I did, but I do now feel I need to chase and remind him several times a day this week to test. I am dying to see what happens through the week as he hasn't tested regularly in ages. It would be so good to see some positive results to give him encouragement to carry on testing. I really do hope that the threat of hospital admission did the trick, that he now realises it's not just me, but that there really is a problem with how he has been handling it and he needs help to sort it all out.
I will of course be there, to guide him on his way, but will be mindful of not overstepping the mark.
