Introvert wedding/ Lack of friendships

I’m about to marry the love of my life in May next year and I’m so so excited to marry him♥️
But sadly the wedding planning process has made me very self-conscious of our lack of friends😔

This never used to bother me until the wedding planning process! Both me and partner are introverts and between us have 4 close friends and 2 more distant friends. The other 100 guests at the wedding will be family, which was important for us to have them there! I’m having my sister as my maid of honor and my husband to be is not having anyone of his grooms bridal party. I’m just so worried about people judging us, and feeling embarrassed about this on our special day.
I’ve tried so hard to let go of this embarrassment and just embrace the few friends we have and enjoy the wedding planning, but the self-consciousness keeps coming up no matter how hard I try to push it down!
Any advice and or first hand experience from couples in a similar situation would be greatly appreciated (please no advice to downsize the wedding as everything is booked and everyone is invited and it’s important for us to have our family there!)😅
