Help!

Angie • I'm 21 years old, married to the man of my dreams. 10.1.16
My fiancé and I are getting married in October, and all the expenses are really stressing us out. My parents have told me they'd help us, but every time I've asked them for help paying for certain things for the wedding, they've always said they didn't have money. So far, we've paid for all the down payments. Now I'm wondering if they're even going to help us at all. My fiancé and I can't pay for the whole thing ourselves, and it's really stressing us out. What should I do?
