You have my heartfelt sympathy. Trying to decide what you want to do for the rest of your life is a daunting task. Believe it or not, I started out as a computer science major until I changed it to Zoology.

There are quite a few opportunities for a Biology major ranging from research to zookeeper. And don't dismiss vet school if that's something you'd like to do, as there are always grants and finanical assistance. My best advice would be to try volunteering, or if your lucky, a job within a career path you'd be interested in. Talk to people that are involved in that profession and pick their brains.
