What you're going through isn't easy. I've had a stutter since I can remember. I know it feels impossible to get out into the world and interact. I think the best thing is to take up a hobby that interests you. A hobby that will get you out of the house and interacting with people. Even if at first it's awkward, everyone has to start somewhere. I recently took up stencil painting which has helped me socialize and network with people that normally I wouldn't really get to meet. I've come to realize that most people are genuinely good hearted.
