Sorry to hear about your circumstances, I can imagine it is really tough and discouraging what you are going through, but you should re-read your posts. People have made some sound suggestions and you just keep calling yourself a “piece of shit”. As others have suggested, post your portfolio so it can be critiqued, be open to moving to new areas (instead of focusing on the “gentrified cities”) and most certainly focus on building your current/new skillset, it might very well pay off, or maybe it won’t, but that is the risk you have to take right now.
There must be something in your resume that is turning away employers if you haven’t gotten a single hit, if you haven’t already, have someone look over it and do the same with your portfolio. Seriously, if you want to get yourself out of this rut, you’ll do this.
I highly encourage you not to throw in the towel yet, but if you decide to, look at community college programs that have an easy-to-get degree in: IT, medical fields a lot of industries out there take minimal or no training to get your foot in the door, but that should be your last option.
