Hi.

There are so many options of things to do in college that it can definitely be overwhelming. It sounds like you are having a lot of difficulty, in particular, trying to decide where and with whom you would like to live when you start at your new school. It sounds like you've been accepted to multiple colleges and the living options would be different depending on which one you picked. Did I understand?
Maybe you could make a list of the options you have, and then make a pros and cons list for each of the options? I usually find I have an easier time making decisions / getting things done when I write them out in list form. College can be a great time to finally go out and live by yourself, but sometimes you feel safer or it is actually safer to stay at home. It depends on your situation.
As far as keeping up with the work...I suggest getting a nice planner and making a to-do list? That really helped me while I was in college. I typically wrote my to-do list in the blank space in my planner, so I could plan out my week based on what I needed to do and it was all in the same place. You want to make sure you are doing what absolutely has to be done first and putting off only things that can actually wait.
Also, as a final suggestion, maybe it would be helpful to have a conversation with your mother and your boyfriend about how you are feeling? They might not realize they are overwhelming you - they might just be excited for you and genuinely trying to help you out. Maybe if you could ask them to give you some space and if they followed through on it, that would eliminate some of your anxiety.
I hope any of that helps.
