I am like this as well! Since I have been back home, I have been focused on trying to make some new friends, as many of the ones I used to have here have moved away to follow their careers. So the "person crush" is definitely a reality, as approaching new people that I know I would like to be friends with can be pretty daunting, as I want to make a good impression not a creepy one. I found the advice in this forum so helpful!!
