I am also a woman and I stutter, the only thing I can tell you is to accept that you will always feel insecure having a stutter, don't expect to get over it one day. But always be proud of who you are and even if you have a bad day, NEVER EVER shut up. You are someone, you exist, with or without a stutter. I have kept quiet for many years, I have isolated myself and it is the worst thing that can happen to you. So continue living and knowing yourself.
