"Ignore her in public" as in you two were walking around in the mall holding hands or you ignored her calls/Skype in public? Does she know you stutter? I'm also in the same position and I hate answering phone calls in public. What I would do is I'd text the other person that I would call them later on. As for depression, focus on building yourself in other areas. Make yourself more of an interesting person. Ask yourself if you would marry yourself, why and why not? Focus on all the Why's and improve on the Why Not's. As for me, I constantly improve myself everyday to become a better person by working out, learning to cook new dishes, taking care/grooming myself, reading self help books, etc. By doing this, you increase your sense of confidence and self-worth by making yourself more valuable. Stuttering is our weakness and there's not much we can do about it as we have limited control over it, however we have control over improving ourselves in all other aspects. In the end of the day, if a girl doesn't like you because you stutter, you're better off without her. Trust me. Best wishes, my friend.
