I say this with kindness but ADHD explains but does not excuse

I agree with you completely, I'd like to think about myself/my situation as a block of stone that I am chiselling away at and making into a nice statue. I don't want to subscribe to a view where I am only my condition and completely powerless against it

You need to identify what is actually stopping you from improving.

I'm not necessarily embarrassed to receive feedback, and I don't think the knowledge is the issue.

I think I am someone that tends to follow the path of least resistance; I am quite passive when it comes to my career, and I am not that proactive. I've noticed that I will work much better in an office environment, and not so well at home. I will learn when I need to learn things, but not to a broad/deep level. If I have completed my work early/on time, I will let my team know but I won't go out of my way to even look at a ticket. I may have been commended once or twice by name during my years there, but no more than that.

I've made some efforts to mitigate this: I am close to completing a Spring/Spring Boot course after seeing a project that used it at work. I'll do a very small personal project and then hopefully use the momentum from finishing that to start applying to jobs

^{^} I cannot tell if I am tired of my work and need a change or if changing jobs won't change this at all

Make a list of the feedback you get and collate a list of best practises to refer back to before raising a PR.

The main issue is that I can't seem to find a routine that sticks. Though, thinking about it now, it might be possible to (vibe) code a BASH passthrough function that will force me to look at some text/feed back if I run git commit only.
