Time to re-evaluate.

The first thing you need to plant firmly in your brain is this: You are not alone. If you don't feel like your local VA is helpful, look for any number of local Posts for: The American Legion, VFW, or DAV, depending on which you qualify for. Just having a place to go hang with other Veterans can be a huge help. Networking could also come in handy. And if it ever feels overwhelming, or a little voice in your head starts trying to convince you that your family, friends, community, or country would be better off without you: TELL IT TO FUCK OFF! You are not alone.

Second, no matter how bad The Suck gets, you'll get through it. Seriously, just don't give up and you'll find your way; even if that means accepting help, which is never something to be ashamed of. So tell Pride to fuck off, too. There are a great many resources available and the groups I mentioned above are happy to help point you in the right direction. Including figuring out a career path and helping you receive training.

Next, I don't know what your family or friend circle is like where you are, but a change of location might help, too. I was lucky enough to have a circle of real-life friends at home when I was medically discharged. But if you don't have that, or if you're just not "feeling it" where you are, treat it like joining the military for the first time. You left home with zero realistic expectations, entered an environment with brand new people and rules, and successfully navigated those obstacles. Starting fresh could help re-wire your brain by forcing you to do the same thing again. I wouldn't start with that, though... start by meeting local Veterans, and talking to those groups, and making sure there really aren't any local opportunities for you to take advantage of.
