"(●¬o¬) (0o0❁)" is an emoticon that does not have a specific meaning or context. It could be interpreted in different ways depending on the situation and the person using it. "I don't want you to be mad at me, you don't know me" is a statement that suggests that the speaker is concerned about someone being angry with them, but also acknowledges that the other person may not have enough information about them to form an accurate judgment.
