self studying many years later (tldr)

I am now longish term NEET, after years of working. Many things went wrong. Unfortunately well into my 30s. Recently, I thought of a goal to work toward with my neet time: learn intro physics (to an undergraduate level... maybe 2nd year?). I've been on wikipedia, youtube, internet blah blah for some time now, mainly pop stuff, not much above dilettante level... would probably fail a gcse exam at the moment.
Apologies for the blog and if it sounds reddit-ish tldr novel, but just wanted to type out some background.
I did take physics at college many years ago, but I was kinda lazy and lacked focus/motivation. I got a 2:2, missed the 2:1 sadly so it was kind of a waste in some ways and I regretted it. Wasn't smart enough to get a 1st or 2:1 while slacking/bunking during those times.

From what little I did learn cramming/mass photo coping notes for exams I've prob forgotten except for surface level awareness of calculus, linear algebra, very basic classical mechanics i.e. not a lot.. Having briefly looked through a late undergraduate thermodynamics textbook I found, I may struggle a bit to solve problems or have much understanding. It may be the case that I'm not up to the task - I think my IQ has dropped somewhat due to age, lifestyle and I suspect it was mediocre to begin with. Also had a fairly heavy alcoholism habit for about 10 years (curbed, mainly). Quite worryingly, my attention span is is shot to shit. But I thought I'd give it a go before I'm forced to get a full time job again, which will likely and sadly be forever. This is just a personal interest, it's likely to have zero impact on any job I work in the future.

I've listed some books, videos below and would appreciate any critiques or advice while I procrastinate for a bit longer. I understand that doing the problems is important, so I realise I have to stop wasting time and do them if my goal isn't pie in the sky. Maybe it will come to nothing, feel free to predict and tell me this.
