I agree that you shouldn’t jump straight into community college classes. Instead, I’d be spending the semester (or more) trying to solve some of the self-discipline problems that were contributing to the problem.
You said yourself that you didn’t attend class as needed, so to me, that screams needing to do something that requires regular self-discipline and routine. Working a job sounds like a perfect solution. You likely won’t be able to get much besides retail or fast food, but that’s not nothing: you’ll still get some work experience and make some money. Honestly, I’d encourage taking on at least 20 hours of work a week while you’re taking your semester off.
At most, I’d say take one community college class. If attention and study skills are your problem, you could attempt to work on improving those. But I’d take it only in something you’re really interested in, and take it pass/fail.
As someone who loves gaming and works at a gaming company, I would also (very reluctantly, lol!) say consider giving up gaming temporarily while you work on building some self-discipline. Although gaming is just a hobby and in moderation can be quite enriching, it does have the propensity to be more habit-forming than other hobbies because of the way games are built (they give you little rewards along the way to keep you playing). You may need to pull back while you are working in good habits, and only go back once you’ve built yourself up with a good amount of self-discipline. It can be difficult to turn the game off at night when you can just get through one more section, lol!
The same could be said if you were staying up all night watching Netflix, though.
