How to interact with people?

As i grow up, i begin to find that ,It is difficult to interact with people. especially in school. Every time i tried to interact with people, i am always scare that i might give an bad impression or might let others think that i am a wierd person. But what i am afraid is not about been dislike by others because i would change myself if i know why they dislike me. The reason i am afraid is that they wouldn't tell me why they dislike me then, talk behind my back and not letting me know the reason. which i see countless of time happen to others. I really want to interact with people but everytime a chance comes up i thought of this, and it stop me from talking to others.How to interact with people?
Listen, you need to be you! Screw what everyone else thinks!!! You can not spend all your life trying to please others!!! They can not be pleased, trust me. You be yourself because true friends love you for you, and you need to love yourself because if you don't how can anyone else.How to interact with people?
You can't please all of the people, all of the time. Don't worry about what others say or don't say. You are not on this earth to live up to their expectations. You are a separate individual, and have the right to be the person that you want to be. If everyone on this earth were the same, it would be a boring world. Believe me, this is all school drama. Things change when you grow up and get into the real world.
don't worry about everyone else just be yourself don't feel like you need to be different to be liked if you do then you're trying to get the wrong type of people to like you...just be yourself and I'm sure Ppl will like you.
People are usually attracted to interesting people. So try to be one. Find interests that expand you as a person, excel at it and make them be interested in what makes you tick. That's when they come to you to 'interact'.
