I was forced to use it, then I was half-taught to use it, now I can use it. Incidentally, I had to use it to get an appointment because of possible ASD... my thoughts went along the lines 'what the heck? Why am I forced to call lots of high ranking strangers when I'm suspected to be autistic?'
Oh well, I figured out how to successfully use the phone. Not to say it always works as well, but the quota is good.
What I always do is this:
1. think about what I want to say before picking up the phone, take my time, get the number and write it down
2. then write down exactly what I want to say, mostly in half-sentences
3. then repeat what I have to say, learn it a bit by heart
4. then make the call, expect to hear a voice answering on the other end and hope I won't hear the busy signal, because I imagined the voice and the buy signal would get me even more anxious
5. not feel embarrassed by anything ridiculous I say but didn't plan on saying
6. the more calls done, no matter if they were good or downright horrible, the easier it becomes to make a call, but wonders are still unlikely to occur: I still hate calls and get all angst-y about picking up the phone.
