Dude start calling people out on their shit. If you keep all this anger built up it’s only gonna make it worse. I stutter too but I’ve learned when people try to take advantage of me for it, don’t let them cut you off or try to predict what ur gonna say. Make them sit there and listen to what you have to say. When it comes to girls I’m in the same boat, but what you gotta realize is that women aren’t something to be worrying about. Focus on what you like to do and make money, that’s all you need and sooner or late the bitches will come to you. It’s also not a bad thing to have friends that are girls rather than wanting sex or a relationship from them. Value your self worth and you will over come this.
