MY BEST FRIEND DOESN'T KNOW ME! please help me friend problems!?

Hm, you have a multitude of cles and recess, strange. I'll just ume you're in elementary school because of the recess thing. These things happen all the time, don't let it bother you, the chances of this happening to you again is A LOT. You guys probably just drifted apart, or maybe she is a jerk. Hang out with new people, you don't need her, she's not an essential like food or water. Confront her when you guys are alone, you can't do it on the phone, it won't work. Ask her why she's been ignoring you and let out all your feelings. You are NOT a friendless loser, SHE'S the jerk, if she was such a big part of your life, she just lost a great friend if you care so much. After you confront her, see how she acts about it, I think you can decide whether she is your friend still. People drop friends and keep friends all the time, it might happen to you but if you feel like dropping a friend, remember what if feels like and don't do it. Best of Luck to you :-)
