You're currently drawing your lack-of-value from your stutter. In an ideal world, you'd realize that your value is intrinsic, and your stutter can't touch it. That's probably a long way off, so start taking an inventory. What do you value about yourself and your situation? If your answer is nothing, try harder! What are you good at? What do you like to do? What is good about your appearance. Now, build on those positive attributes you have, by scoring accomplishments that you back those things up. Get in shape. Join a kickball team. Practice that instrument. Write, if you enjoy writing. Draw, if you enjoy drawing. Sing, if you enjoy singing. Volunteer at a homeless shelter. Learn how to ballroom dance (can't recommend this enough). Do things that you love to do, and that make you feel good about yourself. Beyond that, take on attainable goals, and draw value from your ability to meet them. The truth is that, as far as other people are concerned (even the kind-of-crappy ones), your stutter isn't that big of a deal so long as you bring other positive attributes to the table. Amongst better people, your stutter isn't that big of a deal, full stop. Your friends will even forget that you stutter half of the time, and it's an endearing quality the rest of the time.
