Dear E.,
Reach for the stars, dear, don't stop with your AA, go for a BA, then an MA where you can earn a serious living for the both of you. It's hard being a single parent, so many of us have been there, but it is even harder to want something such as an education and not get there. So, call the nearest four year college or university and speak with a career counselor and ask them the path to on line, or evening courses. Ask them for their guidance, that is what they get paid for, about how to reach your goal. They like goal oriented people, and you have some excellent goals in mind, to be self suporting and, to be educated in your own life and the life of your child.
If you don't get the type of help that is truly useful, don't stop, call another person and another. Do not give up, be resilient, ask about work-study employment qualifications, ask about PELL Grants, they are free, no need to pay them back. There maybe other grants (free money) that are available. Ask about getting help in filling them out, and where to send them and when, the timing is important for the classes you wish to take.
You will succeed, it takes guts to do what you are doing.
Hang in there, I care,
E. H
