Ten years in the seminary and you can only find a handful of Catholics who would really support you on your vocation. Most would surely doubt the quality of your person if truly fit for the "service."
But, what is amazing is that though you will not find that much of Catholic 'supporters' you will surely befriend people whose religious belief is different from yours and yet believe in your perseverance.
This story from Asianews.it is a great example:
The Muslim family of Robertus B. Asiyanto joyfully participated in his ordination in Maumere. His mother laid her hands on the altar: "I'm really happy with my son’s choice". The island of Flores is one of the few predominantly Catholic areas of Indonesia.
