Family member Faker
Guys, I'm (30F) afraid that my 19 year old sister is randomly starting to fake having autism. I'm not sure how to call it out, or if I even should, or if I am even accurate. I don't want to think she's faking. Personally, I feel annoyed to witness it and just simply don't acknowledge the "symptoms". She gets very upset very quickly when I am not accommodating her symptoms like if she is having a "breakdown" it's as if she wants me to baby her.
Okay so obviously I've known my sister her whole life. She's always had a very calm and stable manner of doing everything. Well, she now has her very first boyfriend, and along with this boyfriend came some very loud "symptoms" of "autism". Nobody in our family has ever been diagnosed with autism, but we do have bipolar in our family very heavily.
These symptoms include baby-like behavior, like needing a "blankie", needing headphones to do literally anything, unable to touch anything without gloves all of a sudden, needing help cooking the simplest meals since the cooking devices are too loud, and very exaggerated fake crying fits and exaggerated gagging at random objects. Among other things. I don't know. Can all of these symptoms be masked and then abruptly start showing like this? She was also caught in some lies not too long ago that she was being hit by a roommate, and admitted to this when family stepped in trying to help press charges or yell at the guy. She's only known that roommate for 2 months, he is her friends new boyfriend.
I don't know guys. It's embarrassing as fuck for me to watch. It pisses me off too. All of these symptoms escalate when she is around her boyfriend. I can't tell if she's just trying to convince him mostly or what. Does this all sound very weird to you guys? Should I take this seriously? How would you respond if your sibling randomly started claiming to be autistic and display symptoms that they've never had before?
EDIT: I've also asked our other siblings about this, and all of them were completely unaware that our sister was autistic. (5 siblings and we're all very close, I'm the oldest, the sister I am referring to in this post is the youngest)
