Anxiety about bridal shower this weekend!

Hey, y’all - I’ve been SO anxious about my upcoming bridal shower for the past two weeks! I’m finishing up my last semester of college and am the youngest of two, so my mom is an empty nester, and I know how much joy planning this shower has brought her! She’s had the living room layout setup for over a week now and has been in and out of craft stores and bake shops what seems like everyday! My three aunts are also co-hosting, and I know they’ve spent so much money to make everything beautiful and an absolutely amazing experience for me and and all of the guests, but I’m so worried that hardly anyone is going to show up! They invited 46 guests (all of whom are invited to the wedding, of course - and yes, I sent save the dates months ago), which included my bridal party of 6 (all of whom are OOS, so I didn’t expect them to make it), and so far, my aunt who’s collecting RSVPs has gotten 26 ‘Yes’ responses. Today, my mom heard from two guests that are now going to miss due to Covid, and even though we’re three days out, only four guests have purchased items from our registry (including one guest that RSVP’d ‘No’). I would just be so sad that my family went through all of the trouble to put everything together to have just a handful of people show up, and honestly, I’m also a little nervous about not getting many things from our registry. FH graduated a semester early to start working and saving for furniture and rent while living with his parents, and I’m not starting work until July (our wedding is June 24th), but we’ve never lived together and don’t have much, so we’ll pretty much be starting from scratch. I know no one is obligated to give a gift, but FH and I are funding a third of our wedding costs ($10k between the two of us) for a guest list of 250 people (a LOT of obligatory extended family invites on FH’s side - I wanted a much smaller wedding), and it’s a little scary to think about having to buy all of the basics ourselves while we’re trying to get our financial footing. Any advice or words of encouragement would be so appreciated!
