Ladies I need your wedding help....

I get married in TWO months and I’m am stressing hardcore. I never wanted a big wedding, or even a smaller sized wedding. My fiancé’s family insisted, and even he thought it was right so I went along. Now I’m having a moment of serious doubt. We’re having a 130+ people wedding, church ceremony, big venue, everything I didn’t want. I want to marry my fiancé, I would do it tomorrow! But I don’t want a wedding day of festivities! I have seriously bad anxiety and being in a large group of people, family and friends, or strangers makes me sick to my stomach. I am now starting to feel ill, I can’t sleep, and I just don’t want a wedding day. I want something simple with just our parents and siblings, no big hoorah of a day. I don’t know what to do! My parents will support me no matter what, they’ve already said so, but it’s his family I’m worried about. I don’t know what to do, but I need help! We have a month before we start paying things off in full, and I’d rather put the money to different things, and my energy into us and not a wedding day... help!!!
