General Freak Out

Okay, so last night/this morning I had a nightmare that not a single person RSVPed and since I had never given the venue details in the last couple weeks it was just canceled anyway. I know there are a trillion reasons that couldn't happen, but I'm starting to freak out in general and I still have 6 1/2 months to go. The Knot says I'm over 60% done but I feel like it's still missing a lot. Any advice or even just reading this looooong post is appreciated.

Here's where I am..
Venue/Caterer-Booked but still a significant balance. This also includes seating, linens, etc. They offer some decorations for rent but I don't even know what those things mean. I'm horrible at decor in any aspect of my life and have never even been to a wedding. I don't even know what I want. I don't think I want flowers and we can't have real candles. Also when should we discuss food? We didn't have a tasting or anything because we were more focused on the space as a whole and the reviews are good, but do people normally have tastings if it's built in with the venue? We don't need anything definite til a few weeks before but should I follow up on anything else?
DJ, photographer and videographer-Booked and paidFlorist and officiant-Booked, friends so we've barely discussed pay. We looked at the officiant's book and (kinda) came to a conclusion on which general outline we want but don't know where to go from there. Also, I don't even know if my fiance wants to write our own vows.
Dress-Bought-Alterations Appointment Set. Also do I need to bring fabric or something for my added sleeves? Or is that just in the price? Can my train/hemmed pieces be used for something? Weight loss is a work in progress. Which leads me to my next problem.
Underwear-Bought. Bra-Bought through Amazon and now TWICE they've sent me the wrong size. They're charging for return shipping so at this point I think the universe is telling me to lose that extra back fat. I'm a DDD/F so even with a corset it is an absolute necessity.
Shoes-Ordered-Handmade from out of the country so may be a month and a half stillWebsite/Registry-About as done as I know how. Anyone ever done a private ceremony and address that on your FAQs tab? Dunno how to go about that.
Hotel block-Found what seems to be the best deal, but what if I block too much? I'm not financially responsible but still. And what if it's not enough? I don't expect a ton of out of state family since my sister's getting married 4 months before me and because of the aforementioned private ceremony but of course they're invited.
Save the dates-Sent through email-11 people haven't opened them, a TOTAL of 9 people have given me their addresses for invitations. When should I start asking? Probably sending invitations early July. They are bought and I've begun addressing the ones I know.
Cake-We're in the books but they didn't require a deposit or anything. Probably decided on the cupcake flavors but not our cake. No idea on design. Should I make a payment before? Should I just send them pics of what I think is pretty?Cake topper-Looked at a lot of stuff we like that's VERY expensive. We kinda like the idea of a HP/Star Wars crossover but they're usually custom and handmade.
Stamps-We probably have enough for invitations but not many postcard stamps for the RSVPsWedding bands-OrderedMOH dress (I only have the one)-Have, she will be coming to my alteration appointment. She said she has shoes that will go with it and I trust her.
Hair and makeup-Booked, no deposit required and fairly cheap. Should I try to pay ahead or wait til that day? She says she can get me and my MOH done in 2 1/2 hours. I'm scared that might not be enough, especially since I have THICK, COARSE waist length hair. She doesn't have a trial, should I just go to her salon myself for a "trial" to see timing?
Jewelry-Wearing some of my fiance's late grandmother's. She gave me a lot of gorgeous stuff.
Timeline-No freaking clue. I know the hair/makeup artist is supposed to be at the AirBnb at 1 and the ceremony was supposed to be at 4. Also I heard it's bad luck to do it on the hour? Not superstitious but a little stitious. Haha. Being private and knowing my always late fiance that might not be a problem but I'd be afraid for pictures and stuff. From there, we told the venue 5-9 but that doesn't really include a cocktail hour. Should it be 4-9 so they can show up and relax before we get there?
Alcohol-We know what we want but not really how to go about buying in bulk, especially since it's all available only at different locations. Also, advice for alcoholics that may cause a scene? Or just general people that may make a scene in any way for any reason. There are a few problems we kinda foresee.
As mentioned before, I do have an AirBnb for the night before (with my MOH) and after with my fiance. It's half paid. The other half needs paid a few weeks before.
Also-Super cheesy but cute and comfy silk pajamas are bought. Breakfast food/playlist/any other morning of ideas? What else should I get her as a gift?Do we need a rehearsal dinner for a private ceremony? There will be no processional.Honeymoon-He originally said we should wait because we decided to do Vermont and he thought it would be cold in September-October. Now that he's seen the temperature averages he says let's do it, but he still needs to talk to his dad/both our boss about time off. We want a full 2 weeks but that might not be possible then. But I feel like I should start booking things. Also, I have family there that owns a motel. I think he kinda assumed we would stay there to save, and he wants to pay them SOMETHING but they absolutely would not accept it if we tried. I feel like it's weird to spend my honeymoon with my family anyway. Like, maybe a day or two, but I love everything about Vermont and its beauty and adventure and want to enjoy a honeymoon, not a family reunion. Should we do a week at the hotel with a pool and hot tub and a week at the family motel? Should I keep trying to convince him to stay at the hotel the whole time? When is too late to book? Especially in a place known for its fall colors. That's kinda their peak tourist season. ANY idea what to do about this situation would be helpful. Even if it's romantic or fun ideas of stuff in New England. (Bonus if it's cheap) I think we will be going to Massachusetts during that time and maybe Connecticut or Maine.
Are there any other expenses? We're paying for this completely ourselves which honestly means I'm paying for most of it.
Anything I'm missing? Any advice? Help? What do I do now?
