No one showing up..

We are having a “micro wedding” with just our immediate families (14 attendees). His family is coming from across the country so we rented an air bnb and are going to have our small ceremony and then spend a few days together. Easy enough..
Except for whatever reason it may be my mother has completely changed her opinion on my FH and our wedding plans. She is extremely negative toward all of our plans and feels we made it very inconvenient for our family to get to the wedding (2 hours away, while my FHs family is traveling from the east coast with no issue..). I talked to a friend that was recently married and she said it’s normal for parents to act a little strange leading up to the wedding, so I assumed it was just misplaced nerves. My parents are also planning a small backyard reception for us a week after our ceremony so we can see some family and friends (since we’re only having our immediate families). Well my mom (and now my dad’s as well) attitudes haven’t changed from that negativity and we’re 2 weeks out. My mom is hardly speaking to me which is almost like going through a breakup because we used to talk every day..Here’s the kicker - my dad called me to let me know that he’s stressed that no one will be coming to the reception they are hosting. I was surprised and asked why, and he explained that my mother hadn’t invited anyone except the small list of 10 friends that I gave her. I am mortified. I can’t even bring myself to be excited about the big day because I have this reception looming a week later and I want to cry thinking about how embarrassing it will be. My FH didn’t invite anyone because his close friends are on the east coast. My parents almost have a reputation for their fun backyard get togethers, and I assumed this would just be another one. But now we have a caterer, a DJ, a bartender (all of which I didn’t know they booked until my dad called), and 10 people. I called my mom to ask wtf was going on and she said well i didn’t invite anyone because it’s supposed to be about you (yes, this was said with extreme attitude). anyway, the whole point was for my parents to throw this backyard thing for us with family and family friends and a few of my friends.. At one point they were super excited about planning and hosting but attitudes just shifted a couple months ago. I don’t want to cancel it but I also don’t want to continuing dreading it like I am. I don’t have many friends that live near us and his are across the country so I can’t just send out a mass invite and boost the attendees… Being at odds with my parents, especially my mom, for no real reason leading up to my wedding is hard enough. Now this just really sucks. Not sure how to handle..
