Hi @Melach welcome to Reachout Parent forums!   Sounds like you have a strong willed 14 year old daughter there and yes you are SO not alone !!   Im not sure what your rules are with devices/tv/playstation etc... but my first thought is good old fashioned bribery.   I tell my kids they have no devices until xyz is done. Simple. So they know they have to have done a couple of chores, tidied their rooms, done their homework etc and THEN they can go on their phones/laptops and chill out.   Can you try and get her into a habit of coming home from school and before she takes her bag in her room empty out the food. Do you know why she isn't eating the food? can you slightly tweak what you give her so that she eats it and doesn't bring it back home again? I know that when high school starts they get so fussy and they get embarrassed eating food from home. Or can she make her own lunch?   The lying does become habitual in my experience. It amazes me how much I see my step daughter (13) lying bold faced to her father when I know she has not done what she said.  It blows my mind! Its very frustrating - I feel your pain.   So I reckon barter with the devices, try and set up a routine for her when she comes home from school with the school bag, and sit down and talk about why shes not eating her lunch.   good luck!     ...
