Becoming a priest has it’s downside, just like any career choice. As for the loneliness, that to can happen. But you would have the support of the people and oher priests. Once you get into the seminary, if you find it isn’t for you, you won’t be forced to continue. But if you finish, and take whatever vows a priest takes, it’s meant for a lifetime. I’ve known several priests since becoming Catholic, and there are all shades and strips. There is even one who has since left the church completely. I would go into detail, but I believe that would be very wrong. It isn’t for me to discourage you, but once you’re there, you’re there. I’ll admit that sometimes the people can be discouraging when they shouldn’t be. The priest that left, he had been called in to combine two parishes into one fairly large parish. He had been at a small parish before that. There was too much snipping and all that put into place, and I feel that that was what pushed him away. But any church you go to may have it’s tensions. So, make sure you’re up for it. But it will also bring with it blessings that you won’t get anywhere else.
