Parent with Type 2 Diabetes

Hi I am on this so I can keep updated as my Mother has Type 2 and it is a struggle to support her when she will not let me help her. She has been taking Glucose & Vit c powder out of date and drinking out of date build up as she has been fighting a cold for the past 3 weeks . She is breathless, does no activity is widowed, eats little and often and has a larder full of chocolate! She was in hospital last year and I fear she will be back in again. Refused to see a Dietician last year and a scan at our local hospital. I have asked to speak to her Dr at her Surgery behind her back have I done the right thing? A confused and concerned daughter. She is also hard of hearing and refuses to wear a hearing aid due to Tinitus what can I do?
