You have many options:
1. You can try looking for one full-time job at the moment that utilizes any skill-set you have. If you have extensive experience as a teacher assistant, try finding a JCC to work at. Even if you do not have a degree, many daycares with benefit packages and higher salaries will hire you as an assistant. If you have a skill somewhere else, try looking for a full-time job in that something else.
2. Go to school; the US government pays for vocational training in “high demand” fields that are trying to actively recruit employees in your area. You need to meet certain eligibility criteria. The law is called WIA. They may pay for training in fields ranging from pharmacy technician (which is a 30k salary starting for full time and often can come with insurance benefits/ store discounts). The courses are offered at community colleges and will at least get you a skill so you can have a more stable work schedule. Depending on the program you choose, they may even cover the full cost of an associate degree. Then you may be able to transfer some of those credits to a four-year college to finish your degree. https://applications.labor.ny.gov/ETPL/_rlvid.jsp.faces?_rap=pc_SearchResults.doResultDetails&_rvip=/SearchResults.jsp&index=5&a=cttl
3. You can stop with the certificate or use your new stable work schedule to enroll at a school to finish up your degree.
