Have you been on the addittude mag online site? It can be helpful. And totallyadd.com is good too - it can be really funny, the.lighter side of it all, get your DH to have a look.
There's a lot fo helpful things but also stuff about the plus points of the way your brain works. I get some good ideas from those sites (dont remember half of them like haha) and its nice that its talked about as a difference, with some pros, that you can work with and not something entirely terrible.
My diagnosis has helped me be kinder to myself and realise its OK if things dont get done or I dont manage all the time.
That is so easily translated into making excuses though. Where do you draw the line? I guess my partner continues to support and helps because I am trying so hard. If he was doing everything and I wasn't trying, he'd feel like you do. You've every right to instigate the split if its all gone too far.
I read the important thing was to get the ADHD treatment first as doctors try and treat the depression and anxiety, which are caused by the ADHD, and ignore the ADHD. But I've realised its very important to do both.
Without my anxiety meds, I wouldnt care anymore. I'd have given up. I didnt see how important it was to treat that at the same time at first.
Also, could any of your kids be ADHD with it being highly inheritable? This would be adding more difficulties for you if so?
