I have witnessed her verbally abuse you in vc and then turn it around and accuse you of "ignoring" or being an asshole, turning the blame on you plenty of times homie.

Even in chat she'd bitch and moan about Tryp to the point of interrupting the original flow of the conversation, for lengthy stretches of time. More than once with my limited use of the chat I've had to be like "Shhh, [name] is talking." 

She really is like Med when it comes to self-directing in a conversation, the comparison you made between the two is surprisingly apt. Even her perception of her parents shows similar levels of emotional distancing, over the same subjects even. 

Im pretty disgusted by the fakeness and manipulativeness coming out of her.

She doesn't see herself doing it, that's the tragedy. 

It's "real" to her. 

I have been your friend for years, if you dont care about yourself then please care about us who dont wanna see this shit happen to you.

I have decided to avoid blanc plenty of times because she lashes out at you when you dont give her attention, like I was just ignoring her and talking to Xad and she attacks me and him because shes butthurt nobody acknowledges her. Then when people strike back she cries like a crybully because she is more sensitive than everybody else.

Classic Glass Cannon. 

It doesn't help that she never remembers her bitchy moments, so it always seems "unprovoked" in her eyes. I can ask her like a day or two later why she was so mad at me and she's all like "I dunno" before breezing past it like it never happened. 

While some people prefer to not think about things, she's instead a butterfingers when it comes to holding onto things. 

The bottom line is that shes a toxic abusive tumblr teenager that lashes out at people for not giving a shit about her and victimizes herself when people call her out or dont buy her very obvious lies.

She believes them, through sheer reinforcement and self-ignorance. 

She's more than gone at length about her own self-perceptual blindspots. It's probably part of what has her so singularly fixated on herself.
