Pissed away 5 years

I've been in college 5 years, looks like I have at least 2 more to go if I don't screw anything else up. My gpa is passing but bad. I've had to retake classes. I'm a visual and tactile learner, and don't absorbe anything spoken to me or that I read. The school doesn't care about that even though they say they do. They have always treated me like I'm stupid and just don't want to change their teaching styles to fit me. I was in "special ed" 2nd-11th grade and my college doesn't help those students apparently. Or they don't treat them differently anyway unless you have some type of medical defect.

I'm afraid of failure. If I don't get my degree and license than how am I going to provide for my wife and I? Our house? Kids? Pets? Food? We can't go on living $900 a month, struggling to have enough to eat. That's no life. We're both stressed out and at our wits end and it's taking its own toll on our 8 year relationship. I am so scared.
