Rebbitzen- I understand how you feel and its a very difficult nisayon to still have emunah and bitachon when you see no’s straight out..However, the Novominsker Rebbe said that No shidduch will be pushed away becuase of Diabetes and that anyone that says no to a shidduch because of diabetes it means that the shidduch was never meant to be! Hashem has someone else in mind.
Keep strong you’ll see that when the right one comes along iyh VERY SOON your diabetes will absolutely not get in the way!!
Hashem runs the world and no shidduch is too hard for him to put together! Remember that 🙂
