I have PTSD, but I also was able to lift my family out of poverty and use my benefits to pay for their college. I am currently looking into a benefit for land. I'm in a daily prayer group with different brehs that served.
I fought in wars that negatively affected me, but also opened my eyes to the savagery and love exhibited by humanity. I built a comaraderie with people from different cultures and beliefs. I felt the sting of coming home and being profiled after fighting for the profilers freedom. I saw my wife hold down a household in my absence.
If you don't know how to do what you want to do, it can help you with those skills in addition to life skills.
It ain't for everybody, but it can be if you're desperate enough.
