Friend, everyone is an independent individual, and this independence is very rich. We can start by simply walking independently. You mentioned that people were accompanied by others in the car. What does this mean? Does it mean that you don't know how to get to your destination, or that you are afraid of contact with people, or that you are autistic? All these must be analyzed clearly to solve the problem. If you are really autistic, you should cultivate your curiosity, trust in others and so on. In addition, you can cultivate your hobbies, which makes it easier to make friends. I believe there are still many good people in society, as long as you can do the most important thing without being hurt and then consider others. If you don't have an autistic tendency, you may lack confidence in yourself. In your life experience, you may not have completed a complete thing by yourself. So, you have no idea about yourself, and you don't know whether you can finish a thing or how to deal with something that happens in the middle. This involves another trait that you may lack: analytical ability and execution. That's all we can say for the time being. I don't know if I can inspire you. Good luck! You can contact me again if you need anything.
