I created a file tree that looks similar to my system's file tree, except it only contains all the files that I modified or added and only their respective directories. From there I just use rsync to sync those files/file tree to the system's /.
It's convenient to see what changes I currently have but it requires a bit of manual maintenance. I only really started doing it that way because I was learning how to use rsync and I just kept going on with it because it was working for me.
I'm only working with my laptop, android phone and two Raspberry Pi's so I can get with my little rsync based setup.
Every prescription ADHD drug I tried gave me anxiety and made me pee every 20-40 minutes. Then I'd get more anxiety because I'd have to pee so often. It also made all my normal habits into unhealthy habits. Ever since I took any meds, I've been unable to drink coffee now without the same issues.
Now I just raw dog life. People either accept me as I am or I just stop talking to them because no prescribed pill or social pressure is worth it for me anymore. At least I'm happier now.
