Two words my friend. Embrace it. I know this can be very hard. It took me 27 years to embrace my stutter. No one cares about it man. No one cares about your stutter. I used to repeat conversations I fucked up in my head for months, it was like my own personal hell. Be your own man. Don't try to get people to like. Find a hobby, join a group, try antidepressants, try anything. Get out there man. People who stutter torture them relentlessly mostly because they can't accept that they stutter. ACCEPT IT! Only then can you begin to heal.
