Why the hell ar eyou spending so much time on your DD with her homework??? Cant she do it herself so you can look after the younger children?
Your house need's a bloody routine woman...get up sort one out. Sorry to be so hard but some tough loving is what you need.

get the kids in on stuff. get outside and go for a walk, go to a park and let the kids kick a footy or something. try doing some positive stuff for yourself!

Put C in a carrier if he wants ot be held, you can still do stuff that way. Man Ive got 2 special need's kids and I still do stuff. You are letting the situation get you down...get up or im coming up to drag you up!!!
