so, my best friends old best friend is coming to our school next year and i feel threatened by that, i really dont want to but i do because she has helped me through so much and stuff like that, if her old best friend come and then they start becoming better friends than us, i dont what i would do... im looking for advice... please help me

its natural to feel threatened about it.My advice is that you should try to be friends with your bff s old bff.

i have talked to her once and she doesnt seem like someone i would like... im quick to judge people and im not so sure about her...

I don't think you need to worry all that much. Even if they used to be best friends, they've grown apart. Their bahavior will make it seem like they were the best buds in the world, but that's just nostalgia, something that's nice to dwell in but fades after a while. Even if they get along too well, would it really hurt you that much for your best friend to find someone they like more than you? I understand that you don't want to lose them, and that certainly won't happen, even if they find someone else, there will still be room for you.
Be glad thet they found joy for themselves and try to forge new relationships, losing your bf position is not the end of the world. That being said, I still don't think you have to fear anything.

it will hurt if she leaves me, she is my only friend, the only person i can talk to...

@ShinAttha, you seem to be kind of the counselor on this page, dont you?

I want to help, but I cannot really connect with people in person, so this board is where I feel I can be useful. I am actually very afraid of giving bad advice and changing the situation for the worse.^^
And considering how much you rely on her... I know that a best friend is important and can be the only trustworthy person, but that sounds weird, doesn't it? Think about it, relying on a single person makes them a special someone, but at the same time, you are completely dependent. I am not telling you to cut your ties, but try to rely more on other people despite your best friend and, especially, on yourself. You will be the one that feels down, and you will be the one who decides whether to stand up again or stay down. The future holds so much potential even for a broken heart, it's worth giving it a try.
That's all talk about the worst situation, can you give us an update? Did they already meet or are you still in the calm phase before the storm?

You can try to make friend's with your best friends' friend... If that doesn't work out, just stick with your best friend... Or if you don't want to do that then try to make other friends! (Worked for me)

its hard for me to make friends so she is the only one who is really good to me, i have tried, but i ended up punching my last friend in the face...

>>9 A punch in the face can be justified!
I am a pretty lonely person, that is not to say that I like being alone, but it's hard for me to consider people to be friends. I like to talk a lot, so I am sometimes frustrated at being a shut in, but even I hope to find a friend somedays, and until that happens, I'll manage!
