I’m certain (absolutely certain) that you will feel weird not going to school.
That’s probably some of the value, though. Until now virtually all of your value has been measured in how well you perform at school or in prep for college.
This will be the first year where that’s not the case (or at least not predominant).
If you add some sort of (safe) adventure to that --whether teaching yourself a new cool skill; interning in a national park over the winter; working as an au pair in France – you have a chance to discover some of what you are made of beyond school.
Best of luck with your many wonderful choices ahead.
