Yes... You are definately not alone.
I also hate the phone, but it stems from my inability to say "no" to friends and family. I feel guilty if they want to chat and I'm busy, so I will chat anyhow. I give in to demands, and I find the phone makes it harder for me to say no.
I am getting good at asserting myself, but I still hate the phone for that reason.
I also hate making phone calls because I never know if I will get the person or have to leave a message etc... I never know what the people will say, if I don't know them...
I hate picking up the phone the most because I never know who it will be.
My fear of the phone is due to other issues, I would say, and I am working on those issues. The phone is easier because of it.
It might be the same for you. If you feel like this telephonophobia is harming your life, then I would suggest meeting with a therapist about it, if only a couple of times to discuss strategies to handle it better.
