You did very well in your SMP, and Georgetown has a good track record of its alumni getting acceptances. Not knowing how you described your clinical experience, I can't say how it will be looked at by adcomms. Certainly becoming Complete later has an impact. Hopefully, your Primary Statement wasn't all about your family member and included how you tested the vocation of medicine after you were inspired to pursue it. You still have 6 months of interview season in front of you, so its not time to panic yet. But I think it is wise that you continue to augment your ECs against the possibility of another application season. And if that happpens, applying to DO programs also is a good idea.
Did your Georgetown advisor look over your application and give it a thumbs up? If you worked with clients in the Pharmacy, did you highlight that component of the job so it could be viewed as more clinical experience? Did the sahdowing include an office-based primary care doc (terrific number of hours, BTW). Have you given consideration to broadening your clinical experience beyond patients with neurological conditions with some volunteering in a different milieu, maybe a hospital?
