Indeed it's difficult when it defines so much of your social life. There are two archetypal approaches to that dissociation. The default is fear and shame. When we stutter, we instinctively want to hide from it, avoid situations that force acknowledging it, and turn to parts of our non-stuttering identity to feel better. Courage is not the absence of fear, but the willingness to act in spite of it. Your path to discovering your identity lies in facing and accepting your stutter such that it no longer governs your life so harshly. That said, it's tough to interact with strangers and acquaintances through the blocks, so I suggest close friends; people who you can trust to care about you. For them your stutter is likely a minor inconvenience (apart from causing you suffering) which happens to be a very good mentality to aim for.
