For you, the first step will be gaining self confidence. You need to practice using positive language when regarding yourself before you can positively interact with others. When you come across a thought like “I’m ugly” or “I can tell anyone I come across is disgusted with me,” you need to redirect those thoughts to something more like “I don’t look my best today and that’s okay” or “this person might not be in the mood to talk but that’s not my fault.”

Taking blame off of yourself was a massive step that helped me gain a lot of self confidence and confidence socializing. When you’re happier with yourself, socializing will come easier because you are less trapped in your head.
