REPOST from NWR- Getting nervous hosting my first holiday tomorrow night!

Please talk me thru this- we have been married almost 6 months and I am hosting the Jewish Holiday tomorrow night- YIKES! What was I thinking! I am having 6 people over and I am panic striken! It is not like I never had anyone over b4, it is just a full sit down dinner. I am also doing Yom Kippur break the fast and having 15 people here next week. I am so nervous- please talk me thru this! ( The floor is drying as I am typing this , and the table is waxed!)
