A desire to discuss something that has had a huge impact on your life is perfectly normal.
Empathetic people around would show understanding and at least some interest, at least in the beginning, in attempt to show support and comfort to your plight and trials.
If those around you appear uninterested, and if this is the case from the get-go with them, well.... that says more about them than it does you (you may be surrounded by self-interested people who lack of empathy towards others). However, if they showed genuine interest and empathy in the beginning, and now seem disinterested, perhaps you have been going on too long and "barking up the wrong tree", so to speak, and it's time to engage with other diabetics, diabetic groups/communities, etc... such as here... to gain more knowledge and validation.
