Ok…so it sounds like you have a very very good financial aid package where you currently attend college. Transfer students are not usually that lucky in terms of aid…need based or merit.
The 2020-2021 financial aid forms will use income from 2018. I’m very unclear what that is for your parents. In one post you say your dad retired (when?), but in another you say his income is $30,000. Even $30,000 in income would have given you very significant need based aid at a place like Cornell…unless I’m missing something.
Check to see which colleges provide aid to transfer students. See if there are any that meet full need where you have a chance of acceptance. Apply and see.
I would suggest you not withdraw from your current college until you have an affordable option on your plate.
Why do you need to transfer?
