Okay I am a diabetic woman too. It is a psycho-social illness it is brittle. I was in a hospital for five months last year being treated for my mental health. Then later had a relapse and went back to a different hospital for three months. Health care is expensive though so it's a tough call. If you support her financially she should be spending four hours at the gym. Minimum. Doing stretches and light weights and ten minutes of cardio to start and work her way up to a half hour a day. She needs to be exercising everyday.
Okay the other thing is diet this is huge! Learn about the low glycemic food index and make sure she is eating that and not sweets. It's a hard job my man. I don't follow it all the time but I'm on an antipsychotic called Zeldox 40mg morning and night. I am on an anti-depressent called Effexor 150mg at night. Then I take 2mg of Ramipril which is a blood pressure medicine that protects the kidneys. You can IM me if you want.
What type of insulin is she on? What are her dosages? Does she have an insulin to carbohydrate ratio? Does she use correction dosages? It is very hard for a diabetic to go through this alone and I think it helps that you are around. But I know how expensive health care is. So it is especially difficult. Good luck!
