I only found out recently (it was a sort of family secret, i'm the youngest and a minor still so the side of my family that knew was hiding it from me.) So for the past two or three years my sister has been repeatably "disappearing." she used to live nearly full time at our fathers house but would sometimes go away for weeks or more. I was told she was "visiting her mothers house" and that she "didnt have phone privileges." at the time i did not suspect that anything was wrong. About a three months ago, I was told that she had a mental illness, and that that was the reason she had been gone for all that time. Turns out she spent the periods in various mental hospitals. Now i'm going to point out, my younger self was very, VERY, naive. I recall a point in time where we were in a sort of private waiting room with some of her family (mom, siblings, and stepdad.) we were in there for a few hours and i don't remember most of the time.

Now to describe her symptoms. The (less obvious. sister is mentally sick and huge family secret.) reason i was so shocked was because that day i found out a bunch of things she had told me where lies. Ex: Her (ex) bf. Apparently, she told him a whole bunch of lies about her personal life. I cant be descriptive here, as this isnt my story but he was told that she had a really hard home life, that she was constantly neglected and had to care for herself. We are a middle class family, my siblings and i have always been well cared for and we have an amazing dad who has always payed attention as much as he could. (i dont know anything about her mom, only that she has multiple, but i dont know how many children, and that she didnt really fight for Alicias custody.) actually, i do believe she may have been neglected and undercared for by her mother, but she was rarely over there at all and mainly lived at our fathers house. back to the story, her boyfriend was told that she had a really hard life in general. Now, i dont know exactly what he was told, but fast forward to one day where we have the main focus of the story. My sister told our dad that she wanted him to drop her off at the mall because she had to get some stuff for i don't know what. The real reason she wanted to be there was to "meet up with her boyfriend" i dont know what that was supposed to mean. i have a few guesses that im not listing. basically, she wasnt coming out, (i dont know what she was refusing to come out of lol) and thats when my dad met her boyfriend. after a bit of talk, he cleared things up a bit and im quoting (as close as possible) to what he said. 

"And i was like, 'No, no, no, this is what really happened." After finding out about her real story, her boyfriend ended the relationship. What she told me was that their parents broke them up, that they still loved eachother and that she wished they could be together but couldnt.   
That ended up being a lot bigger of a story than i thought, anyway-   


Her symptoms include excessive lying, shes still too young to diagnose but we think that she doesnt seem to realize that lying is really wrong. her lies include really unimportant things like closely quoting "Despite being the newest cashier at my job i earn the highest wage" for obvious reasons i learned thats not true, and also other things i cant remember. Im not sure if this is related, but she used to be a very misbehaved child. She would bully me by doing things such as holding me down and *licking me* or holding me to her chest and refusing to let me go no matter what. she would also make fun of me and point out certain features on my appearance. ive recently (not actually though, recently is like a year) repeated some of the things shes said like "my feet are super ugly and boney" and she would deflect that and say it was fine and i looked good? also, she once licked her best friend while they were playing wolf in the fifth grade after she told her to stop. 

&amp;#x200B;

im not sure how much ive covered but her symptoms are excessive lying, slight aggression, talking to herself, i believe i heard somewhere that she also has ADD/ADHD but im not entirely sure. she always had mood swings, and would switch between acting mean to me and being kind. she never seemed to know how to stop herself with certain things, she would go a little too far here and there and im pretty sure she used to hate me (i used to be a really big freaking snitch. i regret that now as i got that side of the family into sooo much trouble.) i believe she would also cry a lot, but thats mostly shadows in memories and the occasional recalled story/eavesdrop.

I am not asking for a diagnosis, nor do i expect one. Im sorry if this story sounds unclear, naive, or vague in places, as this covers the span of mostly my younger childhood, ranging from 5 years old to current. Thanks for reading ig?

(for context, the family is fairly fucked up in many areas that im not covering and there has been multiple divorces/early childbirth. All the parental adults involved have been divorce/widowed, and all of my siblings (i have 5, 4 on my dads side so my sis prob has like 8 siblings) and my two nephews, one older and one younger have multiple other siblings, or the older one does as his parents were divorced. its super complicated and im not explaining it here, so bye!)
