You can’t live like that anymore, beating yourself up for stuttering and deciding your life is over before its really begun. Why do you need to live a quiet and isolated life? I stutter and I sure don’t consider myself isolated and quiet. You almost have your degree in accounting but you think you won’t be qualified? Clearly whatever university you’re at believes you will be. So continue on the accounting route, if you end up hating it start moving in another direction.
