Wedding help 🥰

My bf and I are planning on getting married. But I have no clue where to start. I live in Illinois also idk if that makes a difference. Anywho I want like a small wedding just close friends and immediate family I have anxiety and I don’t know if I can handle a big crowd. So how do we plan for weddings paper work, food, music, dress, place? I wanna have a wedding in a beautiful park with our pastor do we make reservations? What paper work do we need where do I get it? Any other things you guys can think of plz comment for us. Thank you 🥰
