Advice on Depression/Anxiety?

You are fighting a culture where we are taught to never quit and persevere. In my opinion you have suffered long and hard enough to ask for help. Your mental and physical health are paramount to you. Take that leap and get help. Dispel any thought that you are at fault, shit happens in life.

I've spent most of my aviation career in a flight company. Flying has been one of the few things that I've been able to use to keep myself out of getting into those depressive or anxious ruts. My head could have me being a complete slug on a given day and then it's time to load up and fly and I get a rocket in my backside. It gives me something to focus on other than the things swirling around in my brain. You've got 2 or 3 other people and a multimillion dollar aircraft that you're responsible for, so there's no time to listen to whatever nonsense your brain is trying to trick you into thinking about.

I got moved to a maintenance company in February because the flight company I was in was deploying but I had a temporary profile so I couldn't go. My first couple months there were horrible because all I could think about was that I had let my other company down and I had lost the one thing that I could say with 100% certainty I enjoyed doing and kept me centered. It took me a couple months to realize that I was an important part of the equation where I had ended up. There were only a couple of us NCOs that the guys had anything remotely resembling trust in. When I saw that, I had to flip a switch. Someone had to lead and take care of those juniors.

You need to do what's best for you in the end. Regardless of which way you decide to go, bear in mind that you're going to have responsibilities. Don't worry about letting the people above you down. Worry about the people below you. If you do that, the people above you will see that and take note.

Also, decide what being a crew chief means to you. A lot of medications will get you grounded, sometimes permanently depending on what they are. DO NOT let that deter you from at least talking to someone if you feel like you need to. Sometimes just talking to a counselor or something can do a world of good.

I think that you should consider that your mental health is an absolute necessity. I would look into different types of therapy options available for you. You should also consider talking to your supervisor about your situation. Not a single leader worth a damn, would be antagonistic to a soldier needing help. They will generally be glad that you came to them for help, before your issues started effecting your work and health. If you're uncomfortable with this, the chaplain can be of great help in assisting you with getting connected with mental health professionals. Obviously, your aid station can also provide you with information that might help. I don't think that you should be concerned about doing this shortly after PCSing. Your mental health comes first. I hope this helps things.
