My best friend left me for no reason and im depressed without her what can i do i want her back!:(?

I've been through this so many times. My best friend since preschool, Sara, would always give us something to fight about but we'd always be BFF's until 5th grade. Then she started hanging out with other people and so did I and then we were soon enough no longer besties. I was so depressed because she wouldn't talk to me alot, but we were still going to each other house and we'd still have fun. But now we don't even talk at all. You should just try to be friends until you two drift even further. Try to be yourself, hang out with others. She's not the only friend out there. All my friends will always be my friends because we have each other's backs. Need more help? E-mail me, Loca_puta_777@yahoo.com
