Allow me to join the United States Military as I am.

Hello, my name is Johnathon Allen Gregory and I have had a very hard life. Way to long to tell, but I have stayed strong through everything that has happened to me and my sister. Some things that would blow your mind, but here I am and since I dropped out of high school to help my mom. I now cannot join the U.S Military. It has been my dream to join since I was a kid. I've tried the Marines and the Army. I do not care which branch. I just want to serve my great country. I scored a 48 on my ASAVB test and the minimal score is 31. So i did pretty good, but now the only way i can join is to get 15 college credits. Which adds up to about one college semester. Unfortunately I am unable to attend college because I have to work full time and do not have the time. I have tried, but it got to hard
