I Hate My Speech Impediment!

Whenever I get stressed, or tired or flustered my speech impediment comes out! I studder, I put words in the wrong places and make up my own words. This does not fair well for conversation or argument for that matter. I was trying to take the bus to my doctor's appointment for my back when I discovered there is only one bus and I missed it on Saturday's. So, in a panic I try reaching my sister no luck, my aunt the same, taxi no luck.. Until, I reached Checker Cab and there was a taxi on the way! Relief, then my aunt and I talk on the phone and she insists on taking me since a taxi is sooo expensive! I have to call back and cancel and the lady yelled at me "THERE WAS A TAXI ALREADY ON IT'S WAY!" I managed to studder out that my aunt was taking me and she hung up on me. Grr. Wish I could just yell at unsuspecting people with out any impediment jeez.
