I just asked this question but I was hoping for a few more answers so here it is:
So my best friend and I havn't gotten along well recently. She pushed me to my limits and I told her that some times she gets me so mad and when she asked I ended up sending a list of negative things(all of which are true and only about 3-4 things over a very large matter e.g. canceling on me for another friend) We both remember one certain situation differently and probably both of us are slightly wrong. This small disagreement turned into a full blown fight and we were physically screaming @ each other. She told me that she can't tolerate me and that we need to f****** stop hanging out for a while and we need a break of each other, me being mad said ok boyfriend and then she got really mad(I would be too, that was a stupid move on my part). Do you think she is bluffing? Let her cool off? Please help, she is an amazing person and I feel terrible but she would never believe me.

Friends should be there for each other no matter what. So if she is really your friend she should take you back. And if this person really close to you and you love her as a family member. Then treat her as a family member. You should protect and no matter what you shouldn't try to hurt a family member. So work it out with your friend.
