That's awful to hear
I've been clinically depressed since I was 15 (I think my childhood of living in different countries every few years did me a lot of favours, but it also messed me up a bit psychologically), and I've been diagnosed with ADSD since I was 30.
The lack of sleep compounds both issues.
Incompletely understand that kids will give you a rough trot, in terms of sleep.
But my boy will give me 2 good nights in a row, and we think we've sorted out the issue, and then he goes months where he wakes up every 40 minutes.
Not only is it not good for me, but it cannot be good for him, either.
I honestly see no light at the end of the tunnel - not to be melodramatic, but it's seemingly interminable.
And nothing seems to work.
When we were reading up on raising a child who is neuro divergent, all the literature kept repeating that it is hard, hard work - they don't understand the world like neuro typical people do, and have stimuli that set them off that most people can't understand.
And they were right.
Not to mention that he's probably tired, and lashing out at daycare because of it.
It's a mess at the moment.
