I was in a similar position as you. I had the exact same thoughts in highschool. I thought I was screwed too. But I came out of it. Join a speech therapy program. Theres a bunch out there. McGuire. Starfish. Open Stutter. Lee Lovett WSSA. Theres a bunch out there. Also go to a stuttering conference or find a stuttering support group in your city. You will meet other stutterers who have become successful in every dimension of life: financial, career, dating, etc. They will show you it is possible to become confident in spite of having a stutter. I know plenty of stutterers who are millionaires. Plenty who do amazing with women, who have had tons of girlfriends.
