I think if you can't find a job and you are aspiring to have other skills but don't have them yet your best bet is a focused job with manual labor as the core component. You might think I'm joking, but manual labor has the benefit of focusing the mind, and there are numerous labor intensive jobs that pay very very well.

Here are three you might consider: working on a fishing boat / working on a oil rig / joining the US Armed Forces.

The first two of those are very good money with a bit of risk with not a particularly long time commitment. After you are out of your financial hole you can transition to doing something else. The Armed Forces is not a bad option if you are looking for something that could be a longer term option for you and potentially include training in skills you are interested in.

Also, in general, getting jobs is first and foremost about confidence. I suspect you don't have a lot, so going out there and doing something where you can build confidence (my suggestion not knowing you is through a body focused manual labor activity, but that may not be the best), and then use that confidence to build skills, and then go out and get a job that makes use of those skills. That's a general strategy that can carry you for your whole life, the trick is to avoid getting stuck in a depressive cycle (which seems like where you are now).

Anyways, good luck mate, wish you the best!
