Overwhelmed By So Much Shit

I'm not even going to get into the bullshit about how my MIL won't even come see her grand kids (it's been over 2 years now since her last visit before this one because she prefers her golden child's kids instead). Omfg. The hoarding tendencies are real! She recently drove to come visit us for a couple of days. She hasn't seen our kids in a few years and she brought boxes upon boxes of shit with her. Shit that I just don't fucking need. We met her in another city and she had her truck and she brought so much shit for my kids that we could barely close the trunk of my sedan because it was fucking stuffed. I sorted through everything before my kids could see what it was. I found tons of fucking Jesus books (we're not religious at all, so those went straight into the bin), tons of little clearance junk items from Walmart and what looked to be dollar store crap, she even put in a Lego set that had a clearance tag that wasn't even remotely age appropriate for my kids. Unfortunately, they found that one and opened it and everything scattered on the floor so I had to vacuum all of the pieces up. She made a big deal about some music box and I looked at it, it was that cheap resin shit you might find at dollar tree and absolutely can not withstand the abuse of a 5 year old. Some other toys that are too small choking hazards for my kids' ages. I am trying to donate what I can, but omfg I'm overwhelmed and angry. I get so upset every time she does this. She'll transport bags upon bags of absolute bullshit across state lines just to dump it all off on us and stress me out. It's such a fucking mess. She'll send shit like that to us too. Just a few months ago, I got some random box in the mail from her that contained old broken toys and stuffed animals that were covered in dirt. I don't fucking understand it. I think she's a hoarder. What the fuck does she expect us to do with all of this shit???
