How much is your family borrowing? Tuition is ~$13k/year. Are you planning on borrowing $50k for your undergrad degree? If you’re borrowing more than the $27k federal student loans, you don’t really have the option of taking 6 years to finish. It won’t be affordable.
It sounds like you need to withdraw and work for awhile then return when you can appreciate the opportunity you’ve been given. But you can’t just drop your classes. You have to file paperwork to formally withdraw from the university or you’ll be billed for the semester. If you miss the deadline, you’ll still be responsible for the bill.
