i am usually a very funny guy and can crack jokes without worrying if it will be funny or not. But one day i do not feel it anymore i do not fell like my happy old self and things kinda get akward with friends because for some reason i cannot be funny anymore. I am a 14 year old teenager and i am wondering if it is a stage of depression or maturity? how can i bring my happ and funny self back? please answer both questions.
