I just found out my grandmother threw out tons of my childhood belongings. I am devastated and feel like I can't trust her at all anymore.

I am 31 years old and I just moved back inside my grandparents' house. For context, my family is a large middle-class family and they (my grandparents) own a very large house for them to live in with spare bedrooms inside it (none of us siblings ever lived with them and it was more of a boarding house for us family members). It has a large attic full of stuff and a basement (which is used for storage)They have spare bedrooms for when we visit and I just moved in under the condition that I need to live there for a few months for work and personal reasons (my brother also lives there, more on that later)<br><br>I got my childhood room back, and my grandmother said she would help me put most of the stuff I left there back when I move to another country and that she would keep it inside the attic. I had to leave tons of stuff behind because I was moving out to study abroad and couldn't take anything with me. I found out that more than half of the stuff I left there is gone, including toys, paintings, stuffed animals, schoolwork, diaries, books, my childhood bed, and other things. I am devastated. I understand she is a minimalist, but it was MY stuff she threw away. To make matters worse, my brother knows she threw everything away and that my grandparents didn't care to keep it for me (my younger cousin is keeping the stuffed animals and my childhood desk). I just feel betrayed and like I can't trust her anymore. I miss my childhood and it hurts to lose all that stuff. I swear, the most epic betrayal is when you are betrayed by your own loved ones. Why would they throw my stuff away? How can I trust her now? I honestly feel like crying and I genuinely want to ask her what the fuck is wrong with her inside. I don't even know if I want to live there anymore. It would be best if I don't say anything and just leave when the time is right, but I just can't keep it inside me and feel like I would explode at any minute. My grandparents are very kind people and I love them to bits, but this just feels like a very personal attack on me. Honestly, I just wanna leave without even looking back at them and never come back again. I would most likely be homeless if I do it, but fuck it, I would rather be homeless than feel betrayed like this.
