Sorry for your loss! If you need anything feel free to message me and talk.
If you are one of the lucky majority that has a state-run medical college, I would highly recommend you apply there. In addition, try for an early decision application if possible. This will be your best shot at an MD. Make sure to mention your situation and point to your otherwise excellent (hopefully) application. Unfortunately the general consensus seems to be ADCOMS are more forgiving of Low GPA/High MCAT than High GPA/Low MCAT. However, until the door is slammed in your face you still have a fighting chance. Do this is only if you are hellbent on applying this year.
Your BEST bet, would be to wait till next cycle, re-take the MCAT in spring, and then apply early next cycle. Apply broadly, mention this experience in your app (how you grew from this, how you dealt with the perceived failure,what positive changes you made in response etc...) The statistics show that your first round through as an applicant carries the highest chance of success, re-applications bring successively lowered chances of admission in general. You should use this gap year to do some work, find yourself, travel, come to terms with your awful loss. Medical school will always be waiting for you, and the more life experience you have the more attractive you are to ADCOMS. There is no such thing as failure, your timeline is your own and nobody can tell you how to live your life. So brush the dirt off, get back up again and get back at it.
As far as DO is concerned, they are starting to catch on to MD students using them as a safety. Many schools want to see DO shadowing experience as well as an LOR from a DO. You need to appeal to their holistic mission and make a strong case that they aren't your backup (Oh S***) option. If you can pull that off, give it a shot, but you're capable of MD with those grades. Don't sell yourself short.
