This is a little harsh, bruv. I applied to 10 clinical psych programs this year, all R1, and have gotten 4 interviews so far (still waiting to hear from several schools). Although my verbal was strong, my quant was in the 43rd percentile. I have great research experience, rec letters, etc. that I think balance it out.
The point is, AMiche, it's more complex than any of us on this side of the game really understand and you can drive yourself wild trying to pinpoint the exact thing that excluded you from the process. I can't tell you whether or not to retake the GRE but have a mentor or someone review your application and see what feedback they have! And know that another year applying is another year building your CV. Good luck comrade!!!
