USMC or Army enlistment possible? Please help.?

To cut to the chase, I want nothing more than to join the military. I was arrested in 2006 for a misdorminor that wasnt violent or anything, and charged with a violation (specifically disorderly conduct). That isn't my problem. I was enlisted earlier this year in the USMC, life was fine, staying out of trouble(i never even really went out anymore, simply to avoid tickets and any problems, I didnt want to lose my enlistment) then of course I get pulled over one random day, I gladly open my glove box for an officer and inside is some of my work tools, one of them being a knife. He got pissed and dragged me out of my truck, I was arrested and charged with weapons posession. They said it was a switchblade. it wasnt a switchblade. It wasnt even close to one, just a small utility knife. To cut to the chase, I had the case dismissed "in the interest of justice" but, and here is my problem, the judge mentioned the military in the court minutes. of course I showed my recruiter and he said he couldn't help me any more. This was months ago. My problem now is that it is driving me insane. I'm having trouble dealing with the fact that I can't serve. That people are enlisting for college benefits and getting in just because they were lucky enough not to get arrested for whatever they did as kids. I know plenty of them. I can't sleep at night knowing that I can't join. I dont even want to do anything with my life, I feel that because I cannot join the military that I am useless, and have no reason to even wake up every day. I didnt think it would be possible to feel this way about a job. I can't watch military movies or hear about the military on tv, I just become more miserable. I realize that the only way out of this, is into the military. I dont really care what anyone says, it is my purpouse in life, and I must achieve it or I have no reason to life. It has gotten that bad. Im hoping someone on here can help me, maybe a recruiter, or friend of one. Is it possible to join stil
