Yea I see where you're coming from. I have a hard time just saying words on the phone. I guess have someone else call if you feel you need to in order to get a job. One thing you culd try doing is just having a conversation with nobody, but just saying words into the phone. Like if you have 2 house phones, just turn one on, talk into the other and just practice hearing yourself and working through blocks and other impediments. I've never tried this, but it kinda sounds like a good idea. Practicing a general outline of what you would say, writing it down maybe and keeping it in front of you. these are things my old speech therapist used to tell me; being the stubborn dumbass I am I never practiced them, maybe this is why it's still extremely difficult for me to talk on the phone. Especially to authority figures and other dominating people.
