You may have ADHD and may want to get tested for it. I'm looking for a doctor to go to again, but being an adult the ones I've seen so far think I just want drugs. Complications from ADHD look a lot like depression.
I did a quick search and came across a few articles such as the following one: https://totallyadd.com/23-signs-you-do-not-have-adhd/
I was surprised to find I exhibit many of these symptoms. Most prominently having stacks of things throughout the office/house which contain various half-worked projects or hobbies or just general information. My shieldmadien constantly complains about the "disaster" and is always shocked when she asks where something is, and I'm able to go straight to the pile of junk which contains exactly what she's looking for.
Other things like time being an elusive concept or going to another room to get something and then getting there and having no idea what I am supposed to be doing are also frequent occurrences. I know where my car keys are, but that's only because I have a very specific plastic tray on the kitchen counter that is supposed to contain them and my wallet. If they disappear from there because I get distracted between walking into the house and emptying my pockets then it's usually a hunt for them.
I tend to bounce between new projects but get obsessively engrossed with them at the start... and then just never complete them.
Not sure if I actually have it, but it is an interesting thought.
Yes, but partially also your existence on HN. Depression/anxiety + well read is almost always some shade of ADHD in my experience (of observing people who get diagnosed by doctors).
Giving up isn't a bad thing. I've given plenty of things up, usually after either realizing I was right or finding someone else had done it.
It an be hard or impossible to combat. I've had people tell me they discontinued their medication due to weight gain (or libido issues, as in this thread).
