Is this a direct snub or am I maybe just emotional?

My work does going away parties, baby showers, gifts, cards, and money collections when people leave, get married, or have a baby. I'm not particularly well-liked because I am the quality control and compliance manager. ***(Edit: I'm friendly with staff but because I'm quality control and compliance, I often deliver data like "Hey, you're behind on your paperwork and haven't done your monthly audit yet. Monthly audits for the prior month are due the final Thursday of the month." It's part of my job to make sure people are doing theirs. End edit. )***

Friday was my last day before going on maternity leave and not a single person said anything. I didn't even get a card. I've been there four years. Last month there was a huge baby shower for a girl who started while she was already pregnant. They had cupcakes and everything. It was so sweet.

I don't expect anything, but this seems like such a slap in the face to not even get a card. No one on the management team said anything either.

So... Am I emotional or would you take this personally too?
