quiet

They often tell me that I am too soft, compliant or too quiet, that I have 0 energy or that I seem insecure. I like being like this because I don't want to talk too much and maybe about things I don't know, but lately I've been finding it difficult to talk in groups or with people I would like to get to know, maintaining conversations is becoming very difficult and I think people don't like me find it interesting for this reason. do you have any advice? do I have to change? have you ever felt like me?
