It might sound obvious, but even if you're someone that likes spending time alone playing videogames/watching series/whatever, do you absolute best to try and spend as much time as possible out of your room for the first ~2 months at college. The first two-three weeks are especially important because that's when people usually make their friends mainly. It doesn't mean you can't make friends later, but it's usually easier the first month because everyone is alone and trying to find someone to hang out with.I am pretty nervous because I am going to have 0 friends, and I will have to make completely new friends which is kinda scary. Also I have gone on like 2 dates in my life so I am going to have to learn how to date from the ground up.
As for things that could go either way I feel like I am going to get a really good roommate or the super Mormon who condones my video game playing as devil worship and reports me to the administration.
But those are just my thoughts, I think I will have a good time despite being nervous for a lot of things. I am pretty flexible so I think I will be fine.
I have always been an introverted person and I still am, but I took a ''hiatus'' from that until I had made some friends.
As for dates, don't worry too much about it, just focus on getting to know as many people as possible, some of them will end up being your friends, others you won't ever talk to again, and then there will be some times when you think there's date potential (just go for it, you really have nothing to lose).
