1) Have your resume redone by a professional. You're obviously trainable and dedicated. A good resume will enhance these things. You don't need to pay huge amounts for this service. Good ones start at just about $100.
2) Don't try to apply for jobs that are drastically above your skillset, especially if you are trying to change careers. Skills in knowing what things to put in each spot on internal forms are tough if not impossible to translate to tech or any other industry. Skills in recognizing where processes can be improved or streamlined translate better. Your resume should highlight and omit the right things. Instead, target positions where you have ~80% of the required skills already and are in the process of learning the other 20%.
3) Consider starting a side business. If you look around there are countless small things that can be done on the side for decent money. Some can even be done with only a smartphone. Others just require a computer. This _could_ end up being more lucrative than a degree for the same amount of investment. The one warning here is don't fall for any "get rich quick" schemes. If it sounds too good to be true, it very likely is. Once you decide to do something, realize that it may take time to build up the income stream. 4-6 months is fast. 9-12 months is more common. If you want to make this about the skills that you are trying to learn then all the better.
