my dh has mental and physical health issues, cant work and isnt really able to parent our kids. i work full time to support everyone. my older teen does so little to help despite nagging /pleading/bribing/etc. the preteen is becoming the same despite sanctions etc. i feel i must have mucked things up to have 2 kids who wont pull their weight /do any chores and who are often grumpy and wont do anything except screens. ive tried to be both parents .ive ended up with kids who seem really selfish and immature . i need some encouragement and words of wisdom
