well, each situation really depends on the person and the seminary, but my general advice to anyone in this situation would be: DONT GO TO A SEM JUST BECAUSE YOUR FRIENDS ARE GOING! Rather, go to the one that best fits you and you know you’ll do great, even if that means going without a friend. In the end, im sure you’ll make tons of friends- you’ll just have to be a little more outgoing then you normally are at the beginning, but after a couple of weeks youll be fine. and because you know that you will thrive there, it will make it easier to be more outgoing and achieve other goals as well.you don’t want to go through sem regretting not being in another place you could have gone to (that was much better for you) but didn’t go because you wouldn’t have a friend with you. so please, DONT FALLOW YOUR FRIENDS TO SEMINARY!
