I understand where you are at! This may not be of any help beyond knowing that you are not alone and hopefully it serves as some motivation to get to studying:
I have a decent profile (I'm not a McNair scholar...but have a masters and years of professional experience as an institutional researcher) and scored probably the same as you on the GRE last year (157v 151q). I was devastated b/c all I did was study quant! Anyway, I was tentative, but my recommenders said go for it anyway, so I applied to 2 strong programs and 2 less prestigious programs. I know that's not many, but I didn't receive even a phone call. So, I took a break and focused on work throughout the summer, then decided last month to go for it again this year! I'm retaking the test in October, and hopefully with a score bump, updated SOP, resume, & LOR, I can get offers from one of the 15+ programs I'm applying to!
Study hard! Taking the test once already should pay off considerably though (at least in your nerves)!
