You commander sounds like a decent guy? Or at least someone I'd not mind meeting.
And trust me - not being responsible to yourself happens. It's not the best habit. At least there is no war here, right now, in a lot of the world. I sent you a list of a couple of options. The last one is a doctor, since - well - war can make that be something you put off too.
The man I'm seeing has a bad habit of - he assumes wanting things is selfish. I, in turn, think my guilt means that I should not advocate for myself. Another friend, who was in the army early, carries a lot of anger. Another one, similar situation, tends to admit to symptoms of being rattled, say, but refuses to admit that something rattled him, because he fears that it's a weakness. So - people do that - look to others before themselves.
It might not be bad, to meet someone? Would that be comfortable for you, not as a therapy sort of meeting. More of a coffee and conversation about - I don't know - light topics?
And that is a good point. Knowing how to make things better if you ever get back home is something that's hard to pick up in the middle of everything. Might be a better chance here.
