when im at school, im really happy with my friends and im always really loud and i laugh a LOT. but when i come home, i basically dont say anything. my parents always yell at me, they say its not good to keep everything in. they're getting worried. theres nothing wrong with me though, i just have nothing to say. what i say to my friends am i really gonna talk about with my dad? thats my problem! i love my family to death, but i dont know what to say to them. what should i do?
