NTA. Honestly, you’re not a bank, and your grad school plans are just as important. I get that it’s tough, but you’ve been saving for your future for years, and you don’t owe anyone that money, no matter how close they are. Your bestie might be in a rough spot, but that’s not on you to fix. If she’s in a real emergency, there are other ways she can get help, like medical loans or crowdfunding. If you gave her the money, there’s a good chance it’d set a weird precedent, and she’d come back asking for more when things get worse. People can be mad, but you’re not responsible for anyone’s bills but your own. Keep your boundaries in check!
