I just found out that about 12 of my close friends had a gr 9 grad party on fri night and i had no idea about it. My best friends didn't invite me. I feel so left out, what if they don't think i'm good enough to hang out with them. what should i do, i'm so upset?

 

Ouch.  We've all been there and know how much that can hurt.  Do you feel comfortable talking to your buds about it?  Even just one of them - you could ask why they didn't think inviting you was a good idea, so you can get their side of the story instead of just wondering.  Or, you could just commit to being an awesome friend from here out to see what happens.  Try calling them to hang out instead of waiting for them to call you (but not TOO often), don't complain too much, and listen when they need someone to talk to.  Have fun and be light-hearted.  And feel free to hang out with other people, too!  Meet new friends in clubs/hobbies/sports and be out-going to invite them to chill with you.  Just don't let it get you down - keep trying!

do you have any tips to be flexible in a short time. and how to do a split too.

Hey babe! The best tip is to stretch daily and frequently! Don't push your limits too fast, but it is important to challenge yourself.  You could try taking a dance or gymnastics class, or for working on your own, try holding a middle split (even if you don't have it all the way) while you watch TV at night!

I have an older brother who is 18, and graduating high school and going to college. My brother and I fight all the time. He stole 5 dollars from me, he broke my headphones and lost my house keys. I am getting tired of hime taking my stuff and I am just tired of him. When we fight half the time it isn't even about my missing things. All i can think about is that the fall can not come quick enough. I want him to move out already. I know it sounds mean but I am tired of being mad at him all the time.
PLEASE HELP ME!!!

As much as I want to say "He's your brother, you should love him!," I totally understand getting frustrated with family members.  Luckily, there's some relief coming soon when he moves away in the fall.  To pass the time this summer, try to spend lots of time outside, with friends, away from the house.  If you start to get mad at him when you're home and feel a fight coming on, go to your room, shut the door, and put on some music until you calm down.  If he keeps stealing or breaking your personal belongings, try telling mom and dad to see if they can help.  But it's only a few months until you can relax - and believe it or not, distance DOES make the heart grow fonder.  You might even find yourself missing him once he's at school!  Just take some deep breaths and be confident that you will make it through the summer just fine <3
