Is there something off about me?

Ever since I turned 13 my life has been miserable, I wasn't always the brightest person, even when I was a kid I never really showed anything that brought me joy, and I think as the days pass I get worser, I don't know why I have trouble showing or feeling happy, I tried everything but nothing seems to work, I just wished I know what's going on with me, why im never excited for anything and feel nothing but sadness most of the time, I wanna laugh and giggle and smile like everyone and at everything but it seems like I just don't get that sunshine feeling in me, sorry I know im overreacting, sorry again,if I am please tell me
