I recommend going back to school for a trade, or a paid apprenticeship of some sort. Could be electrical work, could be some sort of mechanical maintenance, could be plumbing, etc. Machining is another good one. I am sure there are a ton out there that I have no idea about, but that should get you started, then just get on the search engine and start to plow through until I found something.
Maybe it is up to a few years in one trade, and maybe some in another, until you find something that works. Not everything is cut and dry for everyone, the school, shiny degree, shiny job, shitty job??? maybe money, ???maybe waste of time. Same could still apply to a trade(s). I had gone through similar, only to do many other jobs before finding something that worked for me for now, totally unrelated to my education. I had gone to school, which more or less did not amount to much, with more direction, maybe different outcome, but it is the past and we live in the present day and neither the future.
Not knocking formal education, but what I noticed is many of what I learned that was worth anything, especially within biology, chemistry, mathematics, writing mechanics, and other sciences applied or otherwise, can often be learned for free or if you wish to buy books and study on your own, this is also possible. Hopefully for as long as possible.
I hope you find something soon as I was in a bit of a pickle as you were, I stand by my recommendations, even if free time severely limited for awhile. You will have to find what works for you in that limited time, and also gain serious respect for what little you have, especially when after a day and period of time potentially doing labor related work, particularly outside, and with heavy equipment and the elements beating you, and after your body is deciding that anything else is called off for the rest of the day. If in that situation, hopefully it will buy you the time you need to find something better, and then something better, and then, hopefully something better to where you can settle in. Even something like a janitor will still pay, regardless if it does not have all the pomp and circumstance of some kind of CNC design position, etc. I do not mean to be negative, just a bit of a personal example mixed into what could be a general one for many.
You know you, find a place to maintain you, then work from there, hopefully with stable leaps and bounds so you do not fall back. Take care, and to anyone else in this situation. I only know too well the feeling that all the time unbothered to meditate, work out, perform in a variety of arts, do yoga, etc etc would be ideal, but in this existence it seems many of us have to fight to do even that. So if we must do this to move forward in our own individual lives, we must if we wish to progress, and put the energy forth that in better times we will have those ideals we wish for while fighting for them in the life we live in this present moment. To work, eat, wash ourselves, meditate/yoga/perform rituals, sleep, repeat. A tight schedule, but if you try, I do not believe it is impossible, from my experience. Those who do not have to advance in such a way of a very tight schedule ought to feel the most blessed, and make the most of their spare time, where a good lot do not have that, if we can even call it "spare" time, as it fills quickly for those of us who stay on task in Spiritual advancement, even moreso for those who assist in fighting against the enemies of Satya/Zeus.
Hail Satya.
Hail Zeus.
