hey just saw this post and wanted to let you know that I had similar (and even a bit lower scores) but was still able to get in this cycle.
I have a 3.6 cGPA and my B3 was actually lower than yours (3.8). I got in earlier today so I think you have a good chance. I graduated last year and while I did write the optional essay, I didn't write about mitigating circumstances for low GPA (don't have an "excuse" nor felt ethical making something up). I kinda just accepted that I had lower grades and decided to use the optional essay to instead talk about my future goals. My lsat score was 166 so I'm sure you will have a decent shot overall. Best of luck!
