Fight against any negative self-talk. You are an important person - tell yourself that often. To make things work for the better takes dedication, effort, time, and commitment on your part. Be free and open, both with your stuttering and with yourself. Keep moving forward.
Avoidance can be a continuing problem.
Avoidances are signs of listener intimidation, fear, holding back, lack of ego power, etc. The more risks you take the better. Tap into your potential. Do not monitor your speech all the time. This is too hard to do and only becomes a part of the problem and not a part of the solution.
