Advice?..

My wedding is next May we have the deposit down and started planning..lately I have been feeling down, I’m not as close to my bridesmaids anymore and I feel like not everyone is excited for it as much as I thought they would be for us. It honestly made me not want a wedding anymore why so much $ for people I don’t even talk to...it was a dream for growing up but I’m not happy. Not sure what to do
