I'm getting mad that people say I need to be mature
Hey,I just want to say that everyone say that I am 14 so I need to act like it but the reason they say these things are because they always see me playing around and I need to be more mature.It makes me mad when people say this because they don't know my feelings I can't help but always feel happy and wanting to make people laugh just so I won't see their upset or angry faces. I don't like to be serious all the time it feels so intense to me, I'm only serious at important times like at sad times or bad times.My stepsister tells me that I need to be more mature,even though she is 13 she acts like she's all that, and makes herself act like she's a 16 year old teen.When she tells me that I need to be mature we always end up fighting because I get tired of her always saying that I need to be mature.What should I do?
