How do I get others to see inside me accurately.

I feel like nothing g I do is good enough and ppl judge me. To say they aren't us a lie, cause everyone, even ppl in normal situations get judged. We say nobodies opinion of you matters, but we all know thats not true either. How ppl feel about you and around you directly affects your life and quality of life....

My question is ( I figured I'd just ask outright) one are some steps or thi gs I could do to improve how ppl feel about and around me. Im shy, akward, often judged poorly and also ppl don't like me much. Is there anything I should or could be doing to improve how ppl feel about me? And how do you cope in a world your not liked and have no friends? 

I don't think im a bad person,and I don't want to hurt ppl for any reason, thats not to say im perfect cause im not,  I've said horrible things gs in the past, made mistakes as a child and im sure I make mistakes now that I just do t know of yet but I believe the core of me is good. I'd like to make improvements in my life but find it hard cause im in such pain all the time....idk what I can do to improve my quality of life....can someone give me advice please.
