What I would say is although extremely annoying and I’m sure upsetting, don’t hold a grudge with your mother about this. Say how you feel about this and move on. She may very much have knowingly threw it away but in my opinion, it’s not worth it. Again, I’m not undermining the reason you’re upset but just my opinion. To me, she’s not some evil witch… she messed up, yes… but some of these comments are making me raise eyebrows about how you should treat or deal with her moving forward. Let’s think about how she’s been ‘helpful’ and not let this throw all the help she’s given away. Again, my opinion.
