<human>: Can you give me a shortened version of the text?

While my extended family and I have not always spent a lot of time together, I thought we were at least close. My dad and his sisters live different states so I grew up thinking that we just a didn't see each other except for big events. As I got older, I finally realized that it was because my mom really didn't care for my aunts and grandmother or them for her. So they all got together more and we just saw them sporadically. An advantage of being an adult and now having social media is I have been in contact with everyone more on my own. I have always invited them to big events in my life; wedding, showers, graduations, holidays, etc. We had a great family get together last year and I thought I was finally "equal." But I guess not.

My eldest cousin's daughter was married this weekend. And I was not invited. I heard about my parents not getting an invitation and that it was a "mistake." Lots of apologies from aunt, cousin and bride. They finally got one late in the mail but didn't  end up going because it was so last minute that my dad couldn't get time off from work. I never received one so I thought that none of us cousins were getting one because it was a small wedding. Boy was I wrong. I started seeing pics of the wedding posted to social media Friday night, and I see all of my cousins there. It was a HUGE 400 person wedding in a big hall. I even saw a big family picture of how much my cousin loves her "crazy family." Hell, even the part-time colleges of my cousin were there.

Now I don't know what to do. Even though we weren't always together, I thought we were close and family. I've never felt like more of an outsider. I feel like this was all for naught. I was the only one who ever sent cards, but I thought it was just because I was a card person. I feel like I am now without a family and I don't know what to do. I guess I never knew until just now how unwelcome or maybe even unwanted I am in the family.
