How can society empower the disabled?

When I was in university a psychology professor asked the class this question and I didn’t have any good answers…I thought money and political power would help. Now I’m disabled and I was failed from university because I couldn’t cope with the stigma and social isolation… Now I need to be empowered because I want to go back to university but I owe $25,000 in health care and student loans and I was required to withdrawal from university for having low marks and I have to write a letter to the dean explaining myself If I want to ever hope to come back.. I live with my family and I get $1,200 a month in disability and while my expenses are low I can’t seem to save more than $700—$1500 per year… I don’t think That I will ever be trusted with another student loan seeing that I could never make the $350/month payments…I want to go back to high school and retake all of my science classes in order to change my major to outer-Space Architecture from psychology/philosophy…how do I overcome the feeling of dis-empowerment and get back to university…Can I ever get a second chance?
