Wedding jealousy

One of my friends from high school got engaged a few weeks after I did. We haven't talked in a while, actually--we sort of drifted apart since we went to different colleges, and haven't made that much effort to keep in touch. We have very different lives and very different relationships. She and her now-fiance have been dating for over four years, since our senior year of high school, and she's been planning their wedding for almost as long. I've always known they were going to get married, and figured that she would do so before me.

But now that she's engaged, and I'm engaged, I'm feeling this incredible urge to get married earlier, and better, than she does. She posts something wedding-related on Facebook, and I'm just filled with jealousy. I judge every one of her wedding pins on Pinterest to see if it's as pretty, or as unique, or as fun, as what I've pinned that day. I take a LOT of comfort in the fact that her fiance is two years younger, so that even though Dave doesn't have a full time job, at least he's not still a student.

It's appalling, really. I'm embarrassed even to admit how jealous I am. But a couple weeks ago, this friend posted on Facebook about talking to her mom about wedding dresses and bridesmaids dresses, and I was so jealous. Why wasn't I talking to MY mom about wedding dresses and bridesmaids dresses? Well, because I already have my dress figured out, and because I'll probably only have the one bridesmaid (maid of honor), and because I don't need my mom's input on every little decision. I can do this on my own--and I plan to.

Last week, my friend posted something hinting that they've set a wedding date--for a day in July next year. My first though? Oh, I hope we get married in May, then.

Over the weekend, my friend posted some pictures of her and fiance that look like engagement pictures--and one has them holding a bit of bunting with what must be their wedding date (and I was right, it is in July next year). I'm blaming this on low blood sugar, but I actually felt a bit of nausea mixed in with my grumpy jealousy.

What is wrong with me? I'm a normal human and have been envious of other people before--but this is completely out of character for me. Is this a normal part of being a bride-to-be? Anyone else having big Wedding Jealousy thoughts?
