Weddings without the family

I recently got engaged and I've started the wedding planning. My family was very abusive so including my twin sister I had to walk away from them all; not on good terms either as I was forced to get restraining orders on them all.

The last two years the holidays have been excruciating and my birthdays are the worst. Now I'm trying to plan a wedding seemingly by myself. My groom is trying to be supportive and tells me to go to his mom and family and I've tried but they seem very less than interested in any ideas I have. I had my whole wedding idea played out; my twin was my brides maiden and she along with my mom would help me plan it NJ o matter how much they hated me I knew they'd at least be there the day I said I do. Now I have only one cousin and her two kids coming to my wedding that's full of my grooms friends and family. I feel so alone. I feel like I have nothing to look forward to an I'm almost to the point where this wedding just doesn't seem special or fun... all the attention is on my sister in law who's pregnant and deciding to buy a house. Be it I'm ecstatic to be an aunt but my mother in law spends hours talking with her and has barely two words to put in about anything regarding me, my wedding, or my future with my groom. I though maybe she wasn't fond of me but nothing says she doesn't like me.... I know I might seem like I'm being just a bit whiny I'm just not sure what to do.
