I think i better say this in this thread coz i don't think people without anxiety would understand.
It looks like my job is going to change a bit. I'm going to have to start being involved with customers. Basically phoning them and stuff. Which mightn't sound like a big thing, but to me it's huge. I don't know if i'll be able to do it. I'm not bad at my job at the moment and it involves very little interaction which suits me fine. But this is a disatrer. I can't tell my boss because there's no way he'd undersatnd. He makes hundreds of phone calls a day and wouldn't think twice about it. I don't think there's anything i can do about it. It's going to make me dread coming into work every day. Help.
First of all, you will probably adapt to that situation quicker than you'd think. Also, you ahve to identify your primary fear. Will you mess up with something you say on the phone? Will you get very anxious on the phone and feel the need to 'flee'? I think that you have to learn to accept that you might feel anxious from time to time, but that they won't notice and you will take control as much as you can.
get to a CBT cousellor if you can. I have had this problem my whole life but it only really came ahead this year (it used to be an acute thing- i was never shy and always did well in school, but i was a constant worrier! this escalated into full blown GAD and now I'm in therapy and it's the BEST thing for anxiety - don't go to any quack counselor, go to a speicifally trained CBT professional. It will take a good few sessions, but it will work!)
