It really depends. Do hold on and wait for the reply from the department. Chances are they might not consider the grades from the abnormal psych and nursing majors, but they will see them. Explaining your situation on the SOP should help, as should your (stellar!) research experience and (hopefully awesome?) current grades. It doesn't hurt to try. Include a bit more than 3 schools this application season; 5-6 ought to be good. Good luck! Edit: Since this is the SOP forum, I should add that you shouldn't make what didn't work out the focus of your SOP, but rather how it helped build you and your interests right now + how <insert institution/program here> fits into the picture.
