If someone killed themselves over the LSAT, they would have no one to blame but themselves and also do not have enough real problems. It's a test and your score isn't bad. It isn't great, but it would get you into places.
In any case, I suggest doing some background reading about logic and argumentation that is outside of prep books for the LSAT; look up logic books on Amazon. Also, do practice LR questions often. You can improve it to only a few wrong or less if you do A LOT of practice questions (not just tests and timed sections). I had to do about a thousand practice LR questions until I knew the answer every time and only had to bubble in three at the end on average.
Second, make sure you take the test twice. I practice tested in the same five point range basically from the beginning; however, I started out at the lowest score in the range and peaked at a score, but I received an average score and that's what I got on the actual December test even though I was overly nervous on test day and in my opinion, choked a bit. However, my score was sufficient and knowing that will help me in February. I guarantee I will do better the second time around
