One thing that is common and mandatory for everyone that overcame their stutter, is they learned to give f#$& about what other people think or say about them. you need to work on desensitizing yourself from other people's expectation of what 'Normal' speech is. Once you set yourself free from what others say or think, you can actually start making progress. The way I accomplished this is by voluntary stuttering. When speaking with someone, I'd look squarely on their eyes, speak confidently, and voluntarily stutter. The issue arises, when we stutter, and then look away as if we're ashamed of ourselves. The audience picks up on this shame/guilt (not the stutter), and they react accordingly. SO if you stutter confidently, not only you'll feel good about yourself, you'll be well received by the person you're talking to (unless they're bullies).
