Service dog

My name is Mary Thayer.  I'm a type one diabetic on an insulin pump.  I have been a diabetic for 40 years.  Because of the length of time that I've been diabetic, I am now at the point where I can not tell when I am low or high.  After researching and speaking to people, I found that a service dog can help me manage my blood sugars.  I have lost family members under the age of 60 because of diabetes.  I am trying to prevent this by hoping to get a service  dog.  I would appreciate any help that you can give me.   The total cost of receiving a trained service dog is $15,000.   To get a dog, I need $2,500  for a deposit.  Then the dog is trained for 6-8 months.  At the time that I receive the dog, I need to pay and additional $5,000.  After the dog and I receive our training I have 2 years to pay the balance of $7,500.  I know there are a lot of people that request money and I'm from the old school where you do for yourself and I have tried to raise the funds but am having a difficult time.  Again , I appreciate any help that you can give me.  Thank you.
