Sure she said pretty mean and manipulative things, but after learning more about her I started understanding more about why she's like the way she is at times. I'm not ignoring that what she did was wrong, but I'm cutting her slack.
This isn't a blind side.
Since you seem to be ignoring a lot of things here, I'm going to reiterate them.
Tills was lying about Dread and Twente sending her richard pics
Tills said dread sent her a richard pic before but now I can put a face to a name
I've heard the term 'e-whore' to describe her. Probably because she considers herself 'hyperloveual.'
Sending pictures of slit wrists to Brozie

(Source)Being overly aggressive with Brozie.
(Source)and lets not forget when she went around to servers telling people she was going to kill herself.
Bonus points:

(Source)There is a plethora of things that I could add on to this, however, the drama is not about Tills. I'm trying not to over emphasize but I'm sure that I've already hit that point.
Jeetlor: I understand that you're trying to be a nice guy here defending her, but it seems like you're being fooled.
There's no other way to put it than this: Tills is a terrible person. There's no 'understanding' or 'disorder' that can make up for this type of horrid behavior. The way I see it, this is the situation with you and her.
1. She's manipulating you because you're hanging around her.
2. You're whiteknighting for brownie points.
It's really just not worth it Jeetlor. I admire you defending her because you believe that it isn't her fault, but the unfortunate reality is that it is.
