A big hug. I felt like this and my children are not adopted (although one has ASD). It is difficult when one partner works long hours and comes home expecting to be looked after, and everything shipshape, when you feel like all day you've just been in the middle of a raging tornado trying to keep your wig on! When the kids came home from school it felt like they pelted me with all the pent up emotions of holding it together at school. I remember once hiding in the corner of the living room, just to get away from them all (there were three)
My little girl also hated all the food I cooked, and regularily melted down at meals (I think she had a lot of sensory issues) Sometimes I gave her a little meal by herself so she could calm down, and to make meals less of a big deal/compliance issue.
They are all grown up now (terrible teens), and looking back I think I should have concentrated on making after school very calm and fun too, nothing special just a regular routine, with a regular few fun things, watching telly together, making pancakes, hot chocolate a game of snap, a long long bath where they could splash a lot. Nothing too stimulating just a daily framework that they could predict. And most importantly I should have done things I enjoyed. The best times was when it rained outside and I felt I could just give up and be in a cosy put your feet up setting with them, sit on the sofa and cuddle them and watch a film with them or read a story, and not be bustling about. Winter is terribly depressing, I still find the long afternoons after school in the dark hard with my three.
What helps too is now reduce clutter, (but not get hung up on it, untidy doesn;t matter really) make everything simple, ask for little compliance, and go for habits instead (lay the table, put toys away in a big box) Get out for fresh air in the day somehow (you) even if it is just a walk to the postbox for the sake of it. And a friend to meet up with for coffee.
PS. my son (who has some SNs) used to ask to go to other people's houses to play a lot. It was heartbreaking - I felt so upset on his behalf and so frustrated that he didn;t get he wasn;t invited. He liked seeing other people's houses and didn't particularily want them in his own territory. Gradually we worked something out, and invited people over, and he got a few invites back. It will come.
I bet you are a very good mother. Asking for their Dad is something my children used to do a lot; I think it is because the absent parent becomes a bit of a mythological figure/hero. But whenever I did go away, the children used to ask for ME constantly and were very unsettled, so I think you will find you are the rock they depend on.
