Any tips for adapting to adulthood (ADHD)?

I'm a teenager; but I'm worried about my adulthood future because I don't know (reliably) good methods to adapt to my ADHD (and Autism).

I struggle with working on my projects; even when I take ADHD meds (irregularly now), I still struggle with focus. (The result is unsurprising; ADHD meds are usually assistant tools, not a cure.)

<p>I realize that school (grades) have unlikely chances to make actual impacts in my life; I theoretically could just get a job that doesn't require a degree.</p>

<b>I am more worried about how my family is going to react to me failing out of senior year; I am uncertain if I would be able to interdependently live from them.</b> (Independent living is impossible.)

(I (,only <i>now</i> unfortunately,) recognize that the GED exists, but I think it is far too late to take advantage of it now.)</details></li>

<li>I am willing to accept that this is how I am going to live for the rest of my life; <b><i>if</i> there are no other good techniques for adaption.</b></li> <li>Everything feels boring.</li> <li><details><summary>I don't feel motivated to find a job.</summary> There are alternatives lifestyles that don't require a job: <a href="https://wikipedia.org/wiki/Vagrancy">Vagrancy</a>, <a href="https://wikipedia.org/wiki/Vandwelling">Vandwelling</a>, and <a href="https://wikipedia.org/wiki/Off-the-grid">off-the-grid</a> (are examples).

All of those survival styles seem like a pain though. (I haven't tried actually them.) </li> </ul></section>

NOTE: I am trying to avoid toxic positivity.
