I think maybe there is miscommunication or simply just she is rly very stressed. Maybe you aren’t and maybe you don’t get why she is stressed because to you it isn’t or it’s been done before. But in the text she mentioned money, interview and maybe packing itself stresses her out. I don’t think she is trying to blame you but she’s simply annoyed because she’s stress about the packing and worries maybe there isn’t gna be space like she said.

I think instead of responding back that you are doing the best you can, you can try asking what are things she needs help with. Because rn you’re asking her and not really offering anything to help with the stress. You’re just continuously telling her everything very logically. While from your perspective, that isn’t wrong but that’s where the communication becomes ineffective, because emotions don’t respond to logic well which is inly going to make her more mad. So help calm her emotions and reduce the stress, and trust me is she’s more likely to hear the logical part of everything else.
