it’s pretty but i’m sad

i don’t have a picture of my hair before but it was butt-length. i told her to give me layers and told her multiple times to keep it the same length.. she cut it too short for my liking. it’s pretty but i genuinely loved my long hair im sad😭 i know it’ll grow but im worried about when i wash it. i don’t like using heat on my hair and i have wavy hair it’s gonna be a mess
