not qualified for EIC for $155.28?

I've redone my tax return 4 times,  I'm a single mom, raising 2 kids, and I really am bawling. It's saying I don't qualify for EIC for the 1st time ever because of $155.28... this literally will break me this year. I have been waiting on my tax return to fix my transmission.  And because of $155.28, my refund drops to $349. Please tell me there is a way to dispute this???
