Fordham is worth keeping in consideration. It has very good English, history, social sciences. It also has a very good business school. It is a T20 undergrad business school according to Poets&Quants, if you care about rankings. But more important than rankings it has a good reputation among people who actually hire. A person can start out as a history major, and transfer or double major in the business school (Gabelli) as long as you have a decent GPA. It has decent supports for ADHD.
Whatever school you end up picking, the trick is that you must prevent problems, not wait to fix problems. So you start going to office hours the very first week, and go every week whether you need to or not. For papers, you go to the Writing Center multiple times for each paper (planning, rough draft, final read-through.) For math classes, you go to the Math Center at least once a week to check your understanding. You commit to this for at least your first year to get started on the right foot. I disagree with your parents about rigor. You want rigor, and you are smart enough to handle rigor. But you also have to commit to accessing supports before you need them.
