51 years on insulin in Oz.Hi Lm72,
I feel for you. Being a parent and a rock for your son in this situation is a real labour of love.
I can understand a point of view that one injection (the needle for the pump) every, say, 3 days is better than 4 to 6 per day.
Does the hospital actually state why they believe your son is not safe on the pump ? For example, overdose ? And if his anxiety/depression is likely to be at the centre of his troubling level of diabetes control, it seems eminently sensible as @helensarmay has written for a concerted effort for all his health teams to meet and provided a PATIENT-CENTRED CARE approach.
Maybe there are also some NHS-related guidelines which require surrender of the pump under given circumstances such as where the pump is not providing a given level of control?
And I presume he has had blood tests to ensure there is no underlying medical condition(s) causing or exacerbating his anxiety/depression? I was certainly tested as part of my depression work-up.
Do you happen to know what treatment your son is receiving from his psychologist and psychiatrist ? Has it had time to start working.? (My medication took at least 3 weeks to start working and that was prolonged by another 4 weeks when a different medication was prescribed is it was thought it might work better). side-effects were most troubling in the first 3 weeks also.
You mention that he is 'almost 18,' so does his mental health team have any view on his ability to make his own decisions?
I hope your son and you can reconnect soon. He needs you, and his mental health team as his advocates to help sort through this situation which he may view as a sort of punishment, on top perhaps of getting diabetes in the first place.
Please keep writing on the site. We are here for you and your son. Best Wishes.
