I used to do tech support for Mac OS and ya I stuttered but was fairly good at the job as for as helping the customers. I didn't sell much, and probably gave to much free support. My call times where kinda high but It felt good helping people. Then they moved my entire dept to call directing. Which is 90% just telling people they need to pay $70 to be able to talk to somebody for support. So it's just people cussing you out and screaming at you all day. The stress affected my speech to the point I couldn't talk anymore and I quit. It felt like they moved my whole dept just to get me to quit. Oh well that job sucked and there are better jobs. The one trick that kinda helped was turning on my webcam so I could see watch myself talk or maybe using a small mirror. But eventually this stopped working as I just no longer enjoyed the work. I tried to get Xanax from my doctor but they would only give me Zoloft and that did nothing. Looking back I would've tried a couple shots of tequila or something.
