Okay, we talk about BEC situations a lot on hb (see pic for reference!)....But how do you get over it when someone you actually care about has turned into a bitch eating crackers to you?

LOL

One of my closest friends has been a crappy friend to me in the last few months, but she's also a professional colleague, and she's presenting her work at a meeting and I have to go to be supportive...but I really don't want to, haha.

So, how do you snap yourself out of it?
