Shananagrams,
I have definitely been there. Part of the reason I took awhile after college to apply to grad school was dreading the GRE. It turned out that I had a hard time with standardized tests because of undiagnosis dyslexia. I paid a bunch of money to get tested, got accommodations, and did better than I ever thought I could do on the GRE. After the test, I was so excited to contact the application coordinators and POIs to tell them my scores. No one cared.
I mean, you have to show competency (which sounds like your high GPA will accomplish), but depending on the program, GRE scores won't hold you back much.
However, it depends on the school, and I have no experience with history programs. Still, even if you do poorly on the GRE and some schools won't look at you because of that, there will always be others that won't care. Showing that you are a good fit for a specific program goes a long way.
I don't know much about this, but I would be very surprised if you were penalized for having five transfer credits from a community college. That would be pretty ridiculous!
