I’m glad you have a counselor at Purdue who is advising you!
I just have a lingering concern – are your parents going to be willing to continue to file the FAFSA for your sophomore through senior years, based on your plans to sever most (all?) ties with them once you start college? As I’m sure you know, FAFSA needs to be filled out by the parents each year so I am just checking that you have a good plan for that. I know that many students in similar circumstances to you hope they can be declared an independent student for financial aid purposes, but that is very difficult to accomplish and not something that most people can rely upon.
