Anyone every just given up and gone completely sign language

Anyone every just given up and gone completely sign language I am currently at the end of my rope here, I will never be fixed and its frustrating. I currently do not know sign language, but want to start to learn. Has anyone else just given up on speaking? It seems like such a simple solution that I did not think of until now. My stutter has held me back in every aspect of my life imaginable. I am 25 years old and am scared of the world. I feel like this would get me out of my shell, I would have nothing to fear because the biggest phobia(talking), would be completely gone. Also if anyone knows of good ways to learn sign language without a class, it would be appreciated
