I need desperate help and advice on low confidence levels, Please!?

I am in year 11 now at school and have always had lots of friends and i have always been an loud and outgoing person, with confidence. I am intelligent and have a lot going for me. Recently though my confidence has taken a massive dip, I think that every1 hates me, talks badly about me etc. I cant communicate at all anymore and ive lost all my friends. Please help me ....

There must be some reason why you're confidence has dipped recently...maybe someone joked about you and you took it the wrong way and you're just paranoid.





If you focus on this ';paranoia'; where you feel the whole world is against you, you'll end up driving people away and fret so much that you're lacking confidence it will only get worse!





You need to focus on the positive, you said yourself you've always had lots of friends, bright future ahead of you, you're coming to the end of school so a lot of the people you're around at the moment will probably move on.





No one's brilliant 100% of the time, maybe you just ran out of steam for awhile. Part of growing up perhaps? I seriously wouldn't worry too much about it because you'll just fixate on negative and stress yourself further.





Just take a back seat, chill out and try to ';be your old self'; again. Review how you feel in a couple of weeks. Was it as bad as you originally thought? Probably not as bad as you think/feel it is at this moment in time.





If you are really struggling, I suggest you seek further help/advice xI need desperate help and advice on low confidence levels, Please!?
sounds like hormorns or lack of sleep, maybe your should make new friends or friends outside of skool, and the way i see it is i have lots of friends but im my best friend, so if your happy with your self nobody else really matters, im not sayin screw every one and have no friends but do be so worry, once you get to high skool itll be the same way, but im sure you have friends jus stop and think if the things your saying make sense.
