No confidence but anxiety?

So basically, im 18 and im a

student, maybe about a year

and a half ago i was all full of

confidence didnt care what

people said about me, i was a

happy and hyper person, but

then last year (around april

2012) i just all of a sudden lost

confidence and gained anxiety

but what i dont get is im a

happy person never feel down

except for monday mornings

ofcourse. i will try not sound

cocky or anything but i am slim

kinda built, brown hair and

your average joe. so for

example when im in college/

school i would be sitting

randomly in class or in the

canteen and just all of a

sudden i would start getting

flustered and all unsettled and

go very warm and i would be

able to feel my blood pumping

it can get that bad it almost

goes as a blur, it then got

worse where i wouldnt go out

as much, i would eat out,

socialize as much, would refuse

to go get my bus as i was

pretty much scared and i dont

know why! this was a shock for

me as i am VERY chatty and

would say hello to everyone..

and then it just changed where

i was almost scared of big

crowds and people.. it was as

if i was embarrased and shy of

myself which i am not.

summer came it got better

and then i only got maybe as

what i referres to them as

"anxiety attack" i dont know..

but only once a week which

was so releaving better than

maybe twice a day! forgot to

add i would also get red to the

face due to high blood

temperature due to the whole

anxiety problems and worry

over nothing

september came i got back

into college and was grand the

anxiety got better, i now am

actually more confident for

aome reason its as if it just

came back now but.. i am still

kinda scared to go out and eat,

i feel as if everyone ia looking

at me.. and i just cannot walk

through a shop without getting

flustered and all hot i cant

even sit inside anywhere even

if its raining, saying that i could

speak to a wall infact i am

more confident starting

converstations with a

randomer than standing in

silence in a que it makes me

uncomfortable..

So i will hopefully be in uni

next year and i can easily talk

to anyone its juat the randon

flusters i get and the anxiety

thats scaring even when im

asking this it sounds strange as

it came from nowhere!

because i would stand and chat

to anyone and become close to

them in a day i click with

moatly everyone, its just i hate

this anxiety and i want to be

able to actually go to a

restaurant and not leave

because i take a mini attack

thing its stupid i know but has

anyone got any tips or even

know whats going on? and as i

said im very chatty so sorry for

the book Rowal Dahl wouldnt

have a look in! ps. i cant spell

sorry.

Help... please!
