Hey buddy, I may be a world away but I feel your pain.
To start with you are not alone, there is usually someone awake and on this forum, you just have to ask if you need someone to chat to.
Introductions and other posts can get left a week depending on state of mind.
Now to some statements you made.
As far as the VA and medications, well they are just doing a job. They may not do it well, but they are trying. You think about it for a second.
Everybody is different, everybody's conditions are different, and everybody's physical body reacts differently to different meds. And how many hundred thousand Americans, Canadians, Brits, etc served, and how many have problems.
I am in the middle of a change myself and don't like the world or anything in it. I blasted my beautiful wife for the way the kettle was sitting in the corner. WTF is that shit. If one medication does not work, try another, don't just give up, especially raising a child, I know. I raised my son from nine years old as a single father, he is 18 tomorrow. You will find the right combination if you try. Too many people just say f*ck the VA and smoke weed.
Being in the middle of a change, I can't remember whether I changed my clothes in the morning or they were the same ones I used yesterday.
People don't look at you strangely, they look at everyone strange, it's society. f*ck them, let them look, it costs nothing.
As far as being a parent, kids look at us as heroes, my youngest son is 18 today and in Australia, it's old enough to go into a pub and drink, it's old enough to buy smokes and old enough to do a lot of things, he has chosen his life.
Don't worry about the country right now or why they sent you there. You signed the line to do what they said, that's all. Don't get caught up in the political crap. Don't read the bullshit journalists put up.
This is a good place mate.
