We can only play the cards we are dealt to the best of our own ability. Human life is full of cruel, arbitrary, and unchangeable obstacles and tragedies. It's also full of beauty, grace, and moments of joy. Happiness is a fleeting state, contentment is a more realistic goal. Go to your gym as much as you can, it helped me a lot when I was your age. As you get older, people will act better toward you. Perhaps that's because they will suffer their own setbacks in life (death of loved ones, breakups/divorces, miscarriages, career mishaps, etc.) and their teenage aura of invincibility evaporates. Take some solace in the fact that you've made it through the worst part of a stutterer's life, high school. Don't worry so much about the future, the only way to change it is to try your best at whatever you're doing now. For what it's worth, economics and data analytics will offer a lot of options to you, many of which your stutter will have minimal impact on your job performance. I've found that the less I worry about things that I can't immediately change, the better I feel about my life.
