I wanted to share my story with you, it's not entirely the same as your situation but I think it would interest you.
During the first three years after high school I studied in Arts and Sciences and I was forced to withdraw twice from the program. I basically failed every course I took. I think I have something like 13 or 14 F's on my transcript and only like a couple passing grades from those three years.
I took time off to figure myself out and then returned when I was finally serious. I changed to the business program and completed my degree in four years. I averaged a 3.6/4.0 over these four years, but this still only brought my cGPA up to 2.6/4.0. I wrote the LSAT once and scored a 166.
I'm definitely not competitive at every school across the country with my stats, but there are many schools that I am. I have already received offers at four schools for 2019 and I'm hoping to receive some more.
My advice to you would be to go take a couple more years of undergrad courses so you have at least a solid L2 GPA. The cumulative GPA won't matter as much once you have shown that the previous years are not a true reflection of your academic potential. Your LSAT score is incredible and with even a decent L2 would have to make your application hard to overlook. Then focus on applying at L2 schools and schools that drop enough credits to make you competitive like Calgary, Alberta, Saskatchewan, Dal, UNB, Western, Queen's, Manitoba.
Manitoba actually has a "Request for Elimination" you can submit. Based on certain factors you can request to exclude a previous program or portion of your transcript. Also, depending on your reasons for your poor performance before maybe you would be a good candidate for a "discretionary" application at some of the cGPA based schools?
Anyway, just wanted to provide you with some hope. I have a 2.6 cGPA, a 166 LSAT and 4 offers already.
