I have a big fucking issue in my life where my parents don't trust me because i don't do enough time on piano. i know this sounds stupid, but it's a big deal. it effects the relationship me and mom have. and to make it worse, my brother times me so if he gets the timer on his phone incorrect he'll accuse me of being lazy and crap. mostly, it's my older brother's fault for ruining my life.

say it to them how you, with this situation you will have to talk about it face to face with them though i advice you to talk with them without your elder brother around. and maybe it's not just because piano, maybe it's because of something else, this is why you need to talk about it with them on how you feel about this situation

third grade taught me that I can't give my trust to anyone
