I felt like I was blackmailed into rejoining the military when I wanted out. Any help?

I was working at a job when a recruiter asked me to join, and at the time I was estatic about joining. However when asked if I was ready to be shipped off next week I started having seconds thoughts and thought about it for a few days. Then my recruiter showed up at my house and said if I don't go back with him in the recruiting center, he would get fired. Out of pity, I decided to go back only becuase I did not want him to lose his job. After a week after that incident, I was put into DEP as a Reserve. After signing the contract at MEPS and taking an oath, I decided to have seconds thoughts. I told my recruiter about this and told him that I wanted to leave the military and continue with my college. Few days later after that, he came at my house at 11 at night with another recruiter and told me that I had no excuse for not going. When I told them about my decision of not going, they started threatening me of not being a man of my word, and being a coward. I don't know what to do
