Decluttering house

Please don’t judge, so we are getting ready to move and need to clean our lace in order to list it, growing up my mom has always had no respect for my belongings, as a child I can remember her just going into my bedroom with a garbage bag and throwing anything and everything away, it literally gave me ptsd as she would throw away some of my most favourite possessions without a care in the world. Well now she is helping me with my place and she’s doing it again. Throwing everything away. A day planner my grandfather whom died 2 years ago gave me, I still have vivid memories of it sitting on his desk and no she’s thrown it away, old belongings from when I was a child that I wanted to pass down to my son and daughter, she’s thrown away.

I’m having anxiety and panick attacks over this. I wanted to clean my place on my own because I know how she is. Plus I’m an adult I honestly don’t need or want the help.

Does anyone lose have trouble getting rid of sentimental things? Also is it insane of me to feel sad about this?
