DO NOT, and I repeat DO NOT waste your GI benefits on a "railroading degree". Get a degree in something useful that will be applicable to a broad range of career segues. Having a railway specific degree won't help you whatsoever and the schools are scams. Go get a mechanical or civil engineering degree.
I was a Marine for five years and was hired by BNSF immediately out of the Marine Corps without a degree. I was also hired by Union Pacific as a conductor/switchman later on and made 90K my first year of employment. Again, without any degree. Simply coming out of the military is the single best way to get hired by a class 1 railroad. I didn't get a Bachelor's degree until 9 years after I left the military.
>I have severe anxiety and mild depression.
And yeah, so do I. I'd say its severe, even when I was a kid. But I'm 33 and have learned to work through it and not let it show through much. I've had much of it since childhood and it has only gotten worse with military service and railroad work combined with a divorce where I have to give an unemployed ex wife and her unemployed husband half of everything I make to support my "children", who were essentially stolen from me due to the on-call nature of railroad work. I'm only now beginning to receive treatment for anxiety and depression, but it has been there all my life.
So lemme' close this up with a final point of advice. NEVER GET MARRIED, especially in this line of work. you will get fucked hard for your inherent ability to work your ass off and your natural good-nature and generosity. I know that sounds bitter, but it is true. If you want to sky-rocket your anxiety and depression, go get married to a modern woman.
The railroads are great to work for if you are a single guy, and if you STAY single, you can make cash hand over fist and have any material item you want in life. The job is stressful, but not that stressful and if you come out of the Marine Corps, you'll be well adjusted to it. It gets much easier when you start to understand how things work and if you just take it slow. The guys out here are generally cool and won't give you much of a hard time being new. Plus you already have some basic railway knowledge. Just stay single dude and don't pay for one of those stupid railway "colleges".
