I need to do something that matters

I think that is perfectly natural to feel that way. I was mobilized in 2003 for the first time and when I returned to my civilian job, I felt that same way. Instead of doing something good, I was back to making money for my company. That is why I volunteered less than a year later to go to Afghanistan. If you want to continue doing something that matters, look at the VA or even civil service for any of the military departments. I know our Brigade HQs has a contractor IT guy who manages DoD IT access for all of our ROTC programs. In my case, I ended up leaving my civilian job in 2007 (after 11 successful years) and started working as a contractor for the Army with an ROTC program. That gave me some of that meaning left. I am blessed now to do the same work as a GS employee. I hope this gives some ideas and I wish you the best in your decisions.

Look at Oath Keepers. Non Militia. Community service type organization that is defending the constitution as we all gave our Oath to do.

Your enlistment ended but your Oath had no term limits.

Oathkeepers.org.
My local chapter is on FB. Oath Keepers of Greater Wood Co (Texas).

It will put you back into the mix with Veterans, LEOs as well as others who have taken the Oath.

I like the idea that many say about helping veterans especially disabled veterans improve their life. I'm not clear if your looking for a job or volunteer work that is more safisfying (or both) Many vets have started a business doing something they are passionate about like job support for veterans.. Maybe lobby for a cause your passionate about. Maybe inventing something. Maybe pursuing a project at work that you think would make a positive difference for people. Think about what is your dream job and find a job, volunteer program or start a business that relate to or could lead to that dream.

Think about community service. Train others in the IT field or go back to school. Become a nurse or do something in the medical field.

The first question needs to be....what matters?

The civil service is a great way to serve and to make a difference. Who better to support the military than its veterans? Other agencies are also an option too if you didn't want to work for the defense establishment.

There are MANY veterans groups out there that need expertise and knowledge that you could provide. I'd recommend you finding one that suits you and your ideals and run with it. You will find that you're still serving by helping the next generation sort through the BS that we went through. I joined Warrior Pointe (NOT A PLUG), and find that even here I still have some of the same Soldier issues I had while in, (without a 1SG calling me in raising hell), and instead of being SSG Swan, I can still be him with a dose of Matt Swan thrown in. Too many of us need help mentally, physically, and spiritually after 14 years of war, and many have no idea of what life is without a weapon in hand going out on missions, and multiple deployments and redeployments. It's up to us NCO's to bring these guys and gals home mentally and spiritually. I know first hand what it feels like to know your body is here in the states, going through the usual motions, but my heart and mind are still in the Stan.

My take on this is do something to give back that benefits others... financially is great, physically is even better in some ways.. I have ideas, contact me.
