My sister is so fake?

[Your helper]

She is honestly one of the fakest people i know. Here are some examples:
• She says that she hates makeup and she doesn't wear any because she thinks its stupid, then she uploads a youtube video of "her makeup routine" on her "beauty" channel (and she doesnt know that i know about her videos).
• In her videos , she tries to act all "typical little miss cutie" and tries to act all sweet and cute when in real life, SHE IS THE MEANEST PERSON I KNOW.
• With friends, she pretends to be the "loving type" (as in hugging ppl every second) when in real life, she is nothing like that.
• I was talking about this cool actress and she said that she doesn't like her, then she starts tweeting about how cool she is (she doesnt know that blocked people on twitter can read your tweets, and yes obviously she blocked me on there lol)
• She blocked me on facebook so I won't see anything because she doesnt want me to see anything, but if its so private then why does she let everyone but me see it? My friend has her as a friend on there, and she writes words like "what the heck/hell" and she never says that.
• I could write forever about what a fake hypocrite she is but it would take too long.
You might think that I'm just too judgmental, but I learned that from her. She always teases me for everything when in real life, she is the one who needs to be judged. SHE IS SO FAKE IT LITERALLY HURTS. ESPECIALLY WATCHING HER YOUTUBE VIDEO AND WATCHING HER ACT SO FAKE AND EVEN TALK FAKE WAS DISTURBING
I don't really have a question but i just need someone to answer this and idk (words of advice, relate?idk but pls answer).
She is 16 and I'm 14 (both girls) thanks\

bye
