nj & Covid Wedding Anxiety

So, my FH and I originally booked a venue for March 20, 2021 for around 60 guests. We put our deposit down, but with the way things are going we decided to cancel that event before losing any additional money. Instead, we booked a new venue for April 3, 2021. The new venue is a barn with lots of air circulation (the barn opens on three sides, so it's more or less outdoors). The new event is only going to be for 25 people including myself and FH. I am also planning on putting in as many precautions as possible, like masks and hand sanitizers as wedding favors, etc. I am still really anxious about the whole thing and worry that our wedding will accidentally be the cause of someone getting covid. Many of our guests are older and/or at higher risk, so I am hopeful that at least they will be able to get vaccinated before the date. My fiance is really positive and thinks that we are being as safe as we can be and that everything will be fine, but I can't help but to catastrophize. We probably should've postponed to at least next fall, but well, we're on the older side (I'm 37, he's turning 42) so we would rather just get it done and move on with our lives. Is anyone else in a similar situation? Does our new smaller wedding sound like it will be safe enough?
