I believe my stutter is called by anxiety issues… I don’t know if I have generalized anxiety or social anxiety but I can never hold down a job I always quit because I’m very nervous on the job or not comfortable around the other coworkers. My anxiety symptoms are I stutter really bad (hesitant to get my words out). Feel anxiety symptoms around people …nervousness . I’m taking Prozac and Buspirone but I feel they are increasing my anxiety. I hate myself and my life because of my anxiety issues and stutter. As a teacher assistant I have to answer the main phone in the classroom and rely what was said to the teacher. I feel the nervousness come through and I’ll stutter really bad to get my words …block or no words would come out …it’s very embarrassing.
