My mom impulsively got a lot of plastic surgery done on her body and It’s crushing me.

For some reason I feel like l've lost a part of my mom physically. She didn’t do anything to her face yet but her body shape doesn't look like her anymore and I'm trying to accept it but I can't. She was a pretty average weight with a little bit of a stomach, but is also in her mid 50s she also is very pretty and is told all the time by strangers and stuff. She struggles depression, anxiety, and military PTSD on top of the grief from losing her mother only a few months ago. This was an impulsive decision and she’s not thinking straight. She hid it from everyone and even lied to me about the surgery I was picking her up for. So I'm in shock. She doesn't know how this is affecting me as her only daughter on a deeper level. In a way I could relate and feel bonded to her by seeing myself in her features, but now that's gone and it hurts. Im also scared that she could have serious complications for doing so much the same day, at an older age, and not even researching everything before hand. I don’t know how to process it.
