MIL rant sorry it will be long but got to tell someone

I am filled with so much hate for this woman!!!!! How can one person be that hateful, rude, mean, etc. First thing I did wrong, I posted a gofundme page to save my cats life, so I kept it updated on Facebook. Why this is wrong and embarrassing because she doesn't like animals at all. She doesn't understand having PCOS and endo can sometimes stop someone from having kids, so they fill that hole with pets and they become their children and when your child needs something you do whatever it takes to find them help! So sorry dumbass, that that embarrassed you! Second thing I did wrong, I asked how other women get their men to go through their clothes to give away. That's embarrassing and causing a huge embarrassment to her son. I even mentioned that I go through my clothes all the time, I wasn't punishing him, we just need the extra space! We have went from a 3 bedroom place down to a 1 bedroom apartment. This isn't the first time she's done or said crap like this. She has no clue what goes on in our marriage at all. But in her mind he's treated so badly, mentally/physically abused, he has no say in life or the marriage at all, I'm just using him for money (that we don't have), I have some hidden agenda that only she can see and knows about. She has some serious issues!!! This somewhat all stems because her whole life all she's ever wanted to be is a Nana and I am wasting her sons life because that may not happen and along with having serious mental issues, we think it's along the lines of paranoia schizophrenia. But seriously way this much hate towards me. Her son is well taken care of, his needs are always first, I cater to him (I don't mind this), he's honestly just like a spoiled kid! I've blocked her from everything even my cell, but she will just text my husband to get whatever evil thing she wants said across, and she's most likely dogging me to what little family she still talks with. She hates most of her family except her dad but sadly that's only because he's deceased and can't piss her off! Thanks I really needed this off my chest!
