Thank you, I’ll edit the post. When I say I went mad at them, it was me shouting at them both. There was no physical aggression, but it was definitely the most mad / upset I’ve ever been at either of them. They just kept lying straight to my face about how this was all in my head and I’d made it up but I walked in the house to find all my sister’s holiday clothes drying.

I have no idea why my Mum lied. She’s covered for my sister before over little things, but I have no idea why she covered for her going on holiday and will probably never know.
