I had a reusable shopping bag from a. Very specific store that is 8+ hours away from me. It was in my bag of reusable shopping bags, and my roommate told me as she went into the bags that she was grabbing some of them. I told her very specially to make sure she didn’t take that specific bag and she assured me she wasn’t. But I noticed that she had a handful in her hand and didn’t check them as she was walking away, so there’s no way for her to have known if she had accidentally taken that bag or not. Fast forward, and that specific Bag is missing.
There’s a metric ton of meaning/memories I have wrapped up in that bag, as it serves as an emotional/mental anchor of proof that something happened that I’ve had trouble in the past remembering as having happened due to repressed memories. I understand it’s my fault that I left the bag in with the rest of my personal shopping bags, but still. I told her not to take that bag and she couldn’t even be bothered to check. Am I overreacting? It’s just a bag, but it’s also a significant mental anchor for a repressed memory.

Edit to add: this was a roomate/ tenant renting a room in a house I owned. Not a shared apartment or residence.

Also, the problem wasn’t that she took a reusable shopping bag. It was that she was told not to take a specific bag as she was taking bags, but couldn’t be bothered to check that she wasn’t taking that specific bag.

Apparently I’m too sensitive and shouldn’t have kept a sentimental bag in with the rest of my bags I didn’t intend on sharing with a tenant. Thanks all for the replies. I’m going to stop responding to posts on here now.
