I agree with the statements above. You have to look within as to why you want to do this. Not knowing you, I can't give you any better advice. I can however tell you how I handled a similar situation.
After 9/11, one of my best friends decided to quit the practice of law and become a navy pilot. Halfway through flight training school, he was medically discharged. He put his life on hold for the navy and was suddenly without a job, apartment, etc. Luckily he found another job moved to my town and started dating a classmate of ours. The call of the military and his sense of duty were still great. He ended up joining the National Guard as a JAG. (they had no problem with his health) When he found out a group of Guardsmen were shipping out to Iraq and the Colonel needed a JAG on the ground, he volunteered to go with them. After all he'd been through with the navy, I asked him why he was doing it. He told me that he had a strong sense of duty to defend our country and, more importantly, if he went some JAG officer with a wife and kid could stay home.
Around the same time he joined the National Guard, another good friend and co-worker enlisted in the National Guard. I had serious thoughts about enlisting as well, as I too felt that duty to defend my country. In the end, I decided not to enlist because I have a wife I don't want to leave behind. I do all I can to support those who are fighting for us and I defend our country in a very small way by going into court and fighting a different kind of war for our rights.
I know it is nice to hear other's thoughts, but it comes down to you and you alone as to what is the right decision. Good luck.
p.s. this really is cool:
