How do you cope with this?

Not sure how long this has been going for, but I'll try to make sense...

Lately, I've been feeling like I'm nobody's favorite, or that I'm not the best in anything, and it's been driving me... not nuts, but to the point of depression I guess. I feel like my friends play favorites between me and their other friends, I'm never good enough to make honour role, I've never earned a gold in any karate competition (or any sports event, not counting my grade 3 soccer team, but that doesn't count).

Like today during chapel, Jewel and Jen were sitting next to me, and Jewel had Skittle's that she was sharing with Jen, but when I aksed for some, she was just like, "Well, I promised Jen she could have some", and wouldn't share with me, which got me fairly moody and somewhat antisocial that afternoon.
Then at youth group tonight, I kept feeling like I didn't fit in with any of the kids, seeing as the Lindenites all hang out together and I can't seem to get attention from the PCA/Townie/homeschoolers from 3 Hills. I mean, Heidi and Josiah did some shoulder tag and free spar with me, and Gynelle and Devon and I were giving each other tattoos (with Sharpies), but I feel like I don't have any really close friends anywhere in that group. I wonder if I should quit going...

And at school, Bethany, in Grade 11, kind of understands, and is sympathetic, but when I sit with her and Saralyn at lunch in the hallways, all the popular people come up and hang out with Bethany, and for the most part ignore me. James and Stephen sometimes talk to me, sometimes John, but that's about it. Days like this make me wish I didn't have to go to school... Jared and Josiah are probably my two best Grade 10 friends, and the only thing that we really have in common is guitar and an expressed intrest in the same band that we all want to play in. (actually, they started it...)

At church, the Bridge's and Warkentin's hang out with me, and I have some adult friends, but it's not the same, esp. seeing as my best friends are all Acme/Didsbury homeschoolers. Tom and Dave, they pay some attention to me, but I can tell I'm not a favorite of anybody at school, or church, and seeing as I don't think my brother's like me... I feel like I'm alone, without a real friend anywhere. I'm nobody's favorite, and I'm always second best or worse, never the best in anything. Why can't someone pick me to be their favorite, for just once? I know God loves me, but he can't choose favorites between his children, so that doesn't help me any.

As I type this, I can barely see the keyboard, this is the first real crying I've done, since I don't dare show weakness in public. I don't know why, I just feel like I need to be tough to fit in. It obviously ain't working.

Pray for me, please.
