This issue could be resolved somewhat easily in therapy. What you may be feeling may be just a perception of what people are doing but not accurate. Your sense of insecurity could be fueling this perception that people are being critical. By exploring this in a safe setting you could really examine the reason why you think you are being criticized and how to better handle your interactions with others. You can't guess what people are thinking so you can't change that. this isn't your fault but simply perceptions that may not be accurate or you can find a better way to interact with others. Find someone to help you interact and sitll maintain the innocence about this that you do have.
If this is helpful press accept
what you said doesn't help because it is actually happening it's not perception its real to me. how do you handle it? how do emotionally healthy people handle being called ugly or being rejected?
