I need Help!

So this is my first post...but I definitely need some help...I graduated with a BS in Biology and Chemistry and I have applied twice...once last year to about 5 schools with one interview and this time to 12 schools with well pending consideration for interviews for about 5 of them...my stats are:

MCAT-8,8,8 across the board same in every section
GPA-3.6
Science GPA-3.3

Volunteer exp-
-volunteer in clinics, give to the troops, homeless shelter and variety of other charities

Work experience
-working as a CNA

Research-
working on causes of sarcoidosis for 2 yrs with 2 co-author publications

-I've also done some study abroad

Last time most of the schools told me I mostly need to improve my MCAT and have direct physician shadowing so I've been studying for my MCAT and have shadowed physicians but I need to know if I should do something else. I've also applied to summer enrichment programs and have been denied because well apparently I have a strong application for those

I graduated in 2011 and since then I've worked in research for few months and I've shadowed and continued volunteering..I went abroad with family for few months...now since I don't have my job I am wondering would working as a EMT or something help my application if I don't get in this year?
...*sigh* I don't know what to do...please anyone help
