darling, anxiety is a problem that so many people suffer with, just not many people are honest about and it can get more severe in some cases
your GP can't tell your parents (unless they believe you're a risk to yourself or others). however i'm not sure what the rules are about using links within the mental health service so when you're with your GP ask. but i do know something. telling your parents will probably make it easier for you because they will be there for you and it could be that there are other people in the family suffering from similar problems (it can be genetic). you could ask your GP to give you leaflets to show them if they dont understand it. it's NOTHING to be ashamed of, so don't ever think it is
as MNBstyle said, it's your body kicking into "fight or flight". the symptoms are caused by rushes of adrenaline (which would help us fight/run in dangerous situations). However sometimes it's more difficult to cope with the rushes, and that can be when hyperventilation can kick in
I'm gonna list what i learnt at CBT. people might disagree with this, but it worked for me, k?
-everytime you run away, your brain learns that to get out of a situation, it just needs to give you an adrenaline rush. try (when you can) to expose yourself to situations that make you nervous. personally i had a severe phobia of fire and made myself sit in rooms with candles, sit near candles, sit on a table with candles, light a match, light a candle (sounds long but my case was severe as i was convinced that no where was safe, etc, and it developed into many different fears>>chances are you're nothing like me!!!)
-remember (i think someone might have mentioned this before...) that hyperventilating is the WORST thing that could happen. you cannot die from panic attacks or hyperventilation, even if it does feel like it.
-perhaps try rating your anxiety on a scale from one to ten (my psycologist always made me keep a diary with numbers and argh. but now i find it easiest to rate situations by numbers, than trying to describe to the people around me). when you know the numbers are starting to get higher, try to think of rational ways to calm yourself down. in your room you know nothing's bad is going to happen to you (to be honest i don't know how effective this is for everyone else, but i know a number of people who do it so it's obviously a used technique)
-more numbers!! if you think you are going to hyperventilate, or are hyperventilating, it's good to concentrate on your breathing. this is the sort of hypnotising thing i learnt...
in: 10 10 10 10 10
out: 10 10 10 10 10
in: 9 9 9 9 9
out: 9 9 9 9 9
in: 8 8 8 8 8
out: 8 8 8 8 8....... down to one. just count these slowly in your head
and as carrot said, a paper bag can do wonders! but if you can't get ahold of one easily, cup your hands and breathe into it. it's rather wonderful
-finally remember you're not alone!
if it starts to interfere with your life you should definitly consider talking to someone about it. even talking can make things better. and remember i'm not medically trained or anything so i might actually be talking rubbish
