To be honest, I don't have this kinda problem, but I did encounter so many people with this disorder. And I've helped them get through it. The first thing that you must do is telling yourself that you don't have anything wrong with you. Every disease is psychological. If you tell your brain that you'll be fine, you'll definitely be fine. But if you persuade yourself that you have something wrong with you and that you'll never get better, that's what will happen. So tell yourself that you're a confident young man and that there's absolutely nothing wrong with you. The second thing that you must need to do is don't ever give a shit about people. People talk. That's what they do all the time. Don't ever pull yourself back because you're afraid of people's mouth. They can talk whatever they want. You must not care. Because even if you isolate yourself from people fearing what they'll say about you, they will talk behind you. That's what humans do. I guess criticizing is born with us. The third thing that you must do is that try to talk to girls that you're most familiar with more. It can be your mom, sister, aunt, cousins, anyone. It can help you communicate with girls. When I say those simply, I make it seem like it's so simple, right? I know, it's very hard. Like way too hard. But what's your goal? To get better right? Then if that's what it takes, I say try it. And hey, you even posted it on ask anything. That's one huge step. That's how eager you are to be changed. Try your hardest to beat your goal. You'll be proud of yourself at the end. And I know you will.
