So there's a realy nice person in my school and, I see her a lot but I just can't talk to her when her friends are nearby and I just lose all of my confidence when i'm near her even when we are alone or with her friends in the company so what should i do?

Hello from a girl!! If they're anything like anyone I know or myself, she'll appreciate you just talking to her! Obviously try to be nice, and maybe try to talk about a few things you know she likes. But, if you don't know much about her interests, don't try to change yourself by learning it all. Sounds dumb, I know, but you won't believe how many times I've seen that. But, to put it simply, just approach a girl like you'd approach another guy, if not a little nicer.

Another girl here, ello but I agree with Mako, just talk to her ^^. Be nice and calm, don't worry to much since I bet it will be fine. Just act like yourself, find some things you guys have in common. I wouldn't be worried or lose confidence since if she is a really nice person then it should be fine. Just take some deep breaths before hand to calm yourself down if you feel nervous and tell yourself you can do it.

apreciate your help no like really apreciate it but the problem is that my charakter is very hard to understand and many of my friends can't even understand me, well just to say, no one understands me and thats quite the problem, but i'll be sure to try it (arigato) thank you werry much

talk to one of her friends first? get to know them a bit, so then you've a person to say hi to, they can probs intro you to her if you talk to them in a group setting and you'll have somebody to make you feel less anxious when you talk to her, bingo!! I'm a girl by the way
