I am so sorry for your parents passing.
Do you have something like a GPA?
Go to FAFSA forecaster to see what your EFC (minimum amount a college will expect YOU to pay).
Then each college decided how much they give you.
You will check the box “Independent” on FAFSA (category: orphan) - only your income will matter to decide what that etc is. Colleges that “meet need” promise to give you grants (not loans, except for 5.5k in federal loans).
I agree it might be easiest for you to attend a local community college. For the degree and job you want, being in class and dealing with people will matter.
Beware of so called ‘for profits’. As the name indicates they’re not in it to educate you but to make money off of you. They live to pray on young adults who don’t have parental guidance warning them off.
You may want to go to your local hospital and ask where they hire their medical interpreters and what sort of background they have.
