little seeking advice

hi :3 i've been in a ddlg relationship w my daddy for about a year now but we've come across some problems

he makes me food and does my laundry and takes care of me but feels like i don't appreciate him enough bc in comparison i do barely anything back recently :<

and he's more of the (for lack of a better word) stricter (?) daddy type (since he created a job for me so i can work at home but i keep messing up) he tried to teach me life lessons and help me grow up to be better but i don't respond well to it and just get quiet and sad and find it hard to learn and get better

how can i show him i love him without it feeling forced? i always put in more effort after he brings it up but he feels like im only doing it to make him not feel sad, not out of love :<

how can i learn to communicate better when he tries to teach me things instead of getting quiet and sad bc i messed up?

and how can i talk to him abt being a more gentle daddy when in the past ive misbehaved even when he spoke more gently? i don't want daddy to feel like he has to shut down his emotions around me :<

can u guys help me with this im kinda bad at being a good little i don't wanna take advantage of my daddy but i feel like i have been :<
