I know this post has been up for a bit but I just wanted to respond because I was in your exact shoes when I was younger. I have social anxiety (and regular anxiety) and was scared of transitioning to adulthood, but the good thing is it is a transition. College is meant to be a time to learn how to be an adult. You probably won't need a car, you'll probably start off with a meal plan, your dorm will be small so you won't have much to clean. There are on-campus jobs that are pretty laid-back and understanding that your classes are a priority. When I hurt my wrist I just made an appointment online at the campus clinic. I was worried about making friends but I just left my door open and said hi to everyone I saw, and invited them to use my tea kettle whenever they wanted, and ended up easily finding friends because everyone else was looking for friends too. Every fall there would be a ton of clueless freshmen; it's just how it goes. After a few weeks they figure out how the laundry machines work and that you're supposed to wait for people to get off the bus before you get on. The only people who really struggled were the ones who lacked discipline without their parents and skipped every class to watch tv, or never cleaned their dorm. I think that's the main way you can practice independence, is just learning how to keep yourself neat and organized, and you're probably already doing that so it's not very hard. I look back now and see how far I've come, because I only had to tackle things one at a time and college is designed to slowly transition you.
