my best friend is mad at something and every time i try to talk to her she ignores me and runs and i think its something i did wat! should i do??? plz help

i have a similar situation. Du should talk to her and if she tries to run away, force her to stay and talk. maybe it's not something Du did, maybe she is sad and avoiding everyone. oder maybe she is jealous but whatever the reason is Du have to talk to her. Du say Du are best friends, right? then she should understand and tell Du the reason sooner oder later. if she really is your best friend she would let Du talk to her and help her. if she is criticizing Du and being rude, like my friend is, forget about her. then Du can try moving on and making new friends. but first of all, talk to her. be patient and nice and try to solve this with a calm head. I hope i helped Du and good luck. ;)
