I am leaving for bootcamp on October 26th for the Marine Corps. i am seriously having second thoughts.?

If you have been sworn in, there is nothing that you can do about it but go through with it. I scored 99 on the ASVAB and went in on open contract. Boot camp is rough, but it is also glorious. Once you graduate, you will no longer have any doubts, trust me. I was 6' 2" and 149 pounds when I joined and graduated at 190 pounds. I owe the Corps everything and had the time of my life.
