I hear you. I understand that ADHD is an executive function problem, well informed. The guardrails have been in place for years. We have provided tools. We have provided suggestions. Solutions, and even asked "What would work for you?". We've worked with therapists and psychologists to try to instill habits, but my teen is extremely headstrong and wickedly (falsely) independent. There is nothing more I can do for them unless they want to ask it of me.
My teen learns nothing from their experiences, and does nothing to instill their own good habits. At 18, what else am I supposed to do for them? I've been trying to help for years.
Talk to their psychiatrist about moving them to a non-stimulant
In my state, this was off the table at 16, when my teen decided not to waiver me to advocate for their mental health care because they were (and to some degree still are) convinced that I am the source of all that is wrong in their world. I can't fix that.
All of my experience with ADHD in and around my life I've never met someone as highly sensitive as my teen. I have never met anyone as bad as them. Ever.
Being combative is no way to engage in a conversation. Here's the deal, my teen is an adult now. This post came out of years of frustration, and adaptation, and guard railing, and thinking for them, and being their crutch, and being their advocate. You can blame me all you want, it doesn't change that they are my burden to raise and care for and I have done the best that I can with the tools that I have, which I admitted at the top weren't the greatest. I've tried to put the right people in place to assist where I was unable. What else would you have me do?
Respectfully, take your bleeding heart elsewhere.
