Relax, take the test. Apply to the schools you want, if you get an offer great, if you don't...Don't worry if you don't do well, retest in June and be the first early applicant in the new year!
I am in the exact same boat as you. To be honest, test scores and all. I am going to take it. Most schools do not average LSAT scores and only count the highest, however Chapman and a few others do. That being said. I am going to apply this year…
