What's left of my family

A week or so ago, I started a post about my sister, Kacie.  She is a unique soul who lives in her own little world.  I talked about all of the health problems that have made her what she is.  She is coming to visit this Christmas.  And, I'm pretty excited.  She's a hoot.  And I haven't seen her in three years.

Right after I decided to turn my life upside down.  I up and quit my retail job and searched for that perfect job in advertising.  Kacie came to visit that Christmas.
Let me back up (and I will try to keep it as short as possible), Kacie lived with our mom until her junior year in high school.  I felt there would be more opportunities for her in Atlanta with her dad.  She spent the summer there visiting, seeing if she liked living there with her dad.  During that time, her grandmother fell ill, her dad wanted all of us kids to come see her.
So, here we all are, in Georgia, saying goodbye to our grandmother.  One night, we stay up late, drinking and talking.  Myself, my two younger sisters and our dad.  We ask questions about the divorce.  It had been probably thirteen years ago, but we had a few questions.  I knew what mom said, I knew what I remembered, but we never got to hear his side.  I'm an adult, I know that the truth lies somewhere in the middle.  We were curious.  Kacie, being who she is, likes to stir up trouble.  Not because she's a trouble maker, but because she doesn't fully understand.  In a phone call to an aunt (on mom's side) she claimed we were 'up all night bashing mom.'  Which was not really the truth.  It might have been in her eyes, but there was much more going on.
Before my plane landed in Arkansas, my phone was ringing off the hook.  My mother was pissed to say the least.  I had to remind her that Kacie has an IQ that hovers around 60.  Things are different in her world.  My mother didn't care.  And days before Kacie was to return to Arkansas and start her senior year of school, my mom declared she was no longer welcome in the home.
And she wasn't exactly pleased with me either.
So, Kacie moved to Georgia.  And by moved, I mean, she didn't come home.  Just like that.  My mom packed her stuff, gave it to my aunt, who gave it to me, where I in turn gave to my dad.
And I didn't see Kacie again until she came to visit 3 years ago.  My dad really wanted her to come back and visit for Christmas, but seeing that I worked retail, it just wasn't going to work.  I couldn't spend any time with her if I was working 6 days a week, some for 12 hour shifts.
Until I quit.  So her impromptu visit became.  And it was for 3 weeks.  Which surprised me.  It was a bit longer than I had expected.  I called mom and asked if Kacie could stay with her a few days.  She freaked.  Declaring that this was all some 'master-mind plan' to force Kacie back on to her.
What?
That lady is a big bag o' crazy.
So I said never mind and she stayed with me.
On Christmas day, I was still irritated with my mom.  I mean, it's her daughter.  What the heck is wrong with this lady?
My mom decided she didn't want to exchange gifts with everyone else at my grandmothers, she wanted us to pack everything up and take it to her house, despite us all being right there, right then.
I was tired of her nonsense. (There's so much more, but I assume that you're probably bored by this much already)  So I said I wasn't going to her house.
Kacie, unaware of the fact that my war was over her, comes over and says, 'Mom said that she would give my gifts to Nikki [other sister], but wouldn't give her your gifts.'
Ugh. First of all, my mom is the queen of useless gifts and yard-sale treasures.  And I use the word 'treasures' loosely.  She buys used books by authors I have never heard of, clothes that aren't my size or brands I know.  She persists in buying things I liked when I was 12 and have long since abandoned.  I have nothing against used items, just make it something that I like or need.
I say fine, let Nikki take Kacie with her and I wait at my grandmothers house.  I haven't spoken to my mother since.
Two months later, Brad's mom was diagnosed with cancer.  I thought she might reach out to me then.  But she didn't.
Three years have gone by.  My life is so different now.  And Kacie will be coming for Christmas again.  We aren't sure if mom will come to Christmas.  She is fighting with her brother about property.  Kacie stopped talking to her that year after her visit.  And Nikki is currently putting her foot down about her kids.  But those are all different stories that I will try not to bore you with.
