Christie Belle, don't get discouraged. You might have to put off your hike until next year, or you might be able to do only half the trail this year, and complete it next year. There are many people who have done just that.
But CM is right, don't expect others to fund your hike. In fact, be prepared for a chorus of people saying just that. Some of them might not be polite about it, but don't take it personally. Just understand that this type of question comes up on a regular basis. Anytime there's a whiff of "entitlement", it's usually followed by a vigorous effort to snuff it out. You're still pretty new on WB, so we'll forgive you. Try to forgive us, too!
Keep in mind that plenty of people save up their money, buy gear, quit their jobs, and start on the trail, only to find out a few days or a few weeks later that they don't like backpacking for weeks at a time. If it turns out that you don't like it, you may find that the money you've saved is plenty.
