Please make suggestions.

Here's the long version if you want it:
I am looking for an employment network or organization in Boston or Cambridge that might be able to help me pay for a couple semesters of college. I already have a liberal arts BA that's of practically no use finding a job. However, that BA makes me ineligible for tuition waivers by MA Dept. of Education. I also used up ALL other sources of traditional financial aid (including Stafford Loans, Pell Grants, etc.) getting that essentially useless degree.

(I did that because I was only 16 and emancipated when I went to college the first time. I was in an unadopted foster child and knew practically no one in college. My misunderstanding was that all colleges cost the same amount, and that college was a good investment. Worse yet, I was mis-advised that what you major in did NOT matter and all that mattered is that you got a degree... I actually asked everyone I knew and all of my advisers and got this bad advice. Anyway back to my current situation...)

I'm feeling hopeless. Like I said, I am on Social Security Disability and would like to go back to college to get training for a job so I can return to work.

(I called Mass Rehab, but they said they only offer up to $2500 a year in assistance per person. I'm pretty sure that that will not cover the cost of a semester's worth of classes.)

Where can I get college funding if I'm on SSDI and already have a (useless) bachelor's degree? Your suggestions/ideas please.
