I cannot recommend it enough. I have implemented so many of these suggestions. Even better, I've gotten so much healing and freedom from the lies behind my issues and the resulting shame.
I wasn't diagnosed with ADHD until I was an adult. Vyvanse 1000% changed my life. If you have not been diagnosed, please look up symptoms of adult ADHD. They are NOT what I was led to believe in the 1980s and '90s. It was doing an online search after my marriage was being greatly affected, that led me to a diagnosis. I cried and found a doctor immediately.
I also confronted my parents. My dad had been in that old school of thought that I "just need to pay attention more" and "didn't need therapy for being lazy." I'd always had so much shame that I just couldn't "get myself together." The emotional volatility, excess talking, short-term memory impairment, and being late for EVERYTHING, had led to a lot of conflict with my family, and a ton of self-doubt.
Now, I wake up to take my medicine then go back to sleep. The Vyvanse wakes me up about an hour later with my brain firing on all cylinders! I SWEAR to you, I am creating lists of things I need to get done before I'm out of bed. I have my coffee while planning my day and those ahead, then start making those phone calls, etc.,. Those things would have been put off for months before.
The easy-to-implement tips in that book help a lot too. I like how each is only 1-4 pages or so. They are meant to be read one a day. At first I read through a bunch but realized that I wasn't getting as much from it that way. I needed to take a day to ponder what was said. I highlighted a lot.
It comes in print, digital and audiobook formats.
Good luck.
