It was a brilliant decision to get out of your comfort zone and get the new job! It was a conscious decision but now your subconscious is tripping you up. Over years and years of stuttering you have developed certain thought patterns associated with stuttering and you will not be aware of all the triggers and even if you were, you can't recondition yourself by thinking the new, affirmative thought once. Unfortunately avoidance is only ever a temporary fix, it increases stuttering in the long run and shrinks your comfort zone to the poit where you don't want to leave your house anymore. You thought that the decision to start a new life was the big hurdle and it would get easier after that. But a new job doesn't make you a new person. Consistently and diligently working on yourself makes you a new person. It sounds like you could really do with a coach or therapist to help you through this process! All the best, it sounds like you have a lot of courage, don't give up now!
