College fraternity beneficial to an Army veteran looking for community?

25 year old Army veteran (11b) currently utilizing the VR&E chapter 31 disabled veterans schooling benefit to go back to college for my Bachelors in Supply Chain Management. I got an email from my community college where I’m getting my associates from about joining Phi Sigma Pi. I love the sense of community and donating your time and also networking with other people. I don’t have really any friends anymore after getting sober (8 months yesterday!) and was wondering if anyone can share their personal experience with joining a fraternity in their college as a veteran and what positive affect it had on your life.
