Yeah, I have struggled with this for years and I still feel uncomfortable walking outside. One thing I have started doing more lately when walking past people is making eye contact with them. I'll throw them a friendly glance, maybe two if they look friendly. I used to be terrified to look directly at people when passing them. However, I've found that people often appear pretty nice and have kind expressions on their faces when looking at me. It makes being out in public less intimidating and I feel a little better about it every time I make eye contact with someone, especially when people smile at me or ask "how are you doing?" I've also found that many people don't look at others when passing them. I often look at people who are heading in my direction thinking that they're looking at me, too. In actuality, they stare to the side, towards the ground, straight ahead, or at their phones, but not at me. Who knows? Perhaps they are uncomfortable walking around in public too. Some people just hide that discomfort better than others. Us folks with SA tend to jump to conclusions about what other people (even strangers) think of us, but we are not inside their heads. I think that's the key thing to remember.
