AITAH for refusing to give my cousin the money I've been saving for my lifelong dream?

I (20F) have been saving for a study abroad program since I was 18. It's not just a trip - it's been my dream for years to travel, learn, and grow outside of my home town. I've worked endless shifts, skipped vacations, and sacrificed so much to finally have enough money to make it happen. I've been counting down the days.

Enter my cousin (23F). She's recently pregnant and struggling financially. Last week, she came to me asking for money to help with baby expenses. Not a small amount either - basically everything I've saved. She called it "a family emergency" and said it's my duty to help because, according to her, my dream trip is just "a luxury" compared to her needs.

When I said no, she flipped out. She accused me of being selfish, heartless, and not caring about her or her baby. She told me I can just "save up again", like two years of hard work can magically be redone overnight. Then he mom (my aunt) chimed in, saying I'm a terrible family member and that I'll regret this when I', older. My cousin even told the rest of my family, and now everyone is texting me, saying I'm prioritizing a "vacation" over her child's future.

I've worked so hard for this, and I don't feel like it's fair to give it all up just because she didn't plan her life better. But the guilt trips are getting to me, and now I'm questioning myself. Am I being selfish for wanting to protect something I've worked years to achieve?

AITAH?
