Mike,
First off, Semper Sigh Bro!
Secondly, My wife loves me a lot. But she has days where she wants me dead and even says so. She can be loving and mean and hurtful. She is responding in her own way to my PTSD I think. I can't help you out with the family issues, thats your thing to figure out. Just know this, most PTSD relationships dont work out unless the spouse understands the reasons for PTSD and the signs of the stress. There is a video on this site that I would get her to sit down and watch. It wont explain everything, but it might get her to understand why you are acting the way you are.
She could be acting the way she is out of love. I know its twisted, but maybe she is thinking if she gets you worked up you might snap out of the depression.
Depression and suicide are common for all of us in here. Its a demon you have to learn how to fight. You dont get up every day for others, you need to get up everyday for yourself. You are in a different mode of combat now. Its an internal war you need to fight. It will make you stronger and smarter if you can take the challange and fight back. It is how I have survived so far.
It is possable to go long term without treatment, I managed over 20 years. Now that I have admitted that I have this problem, its gotten worse but also better. I have started to understand my past both in my behavior and decisions. In talking to others in here and reading what they write, I can see the same problems in myself.
This is not easy but nothing worth it ever is. This is like your third day in boot.your tired, sick of being yelled at and run everywhere...your head hurts from being shorn and your questioning what the hell were you thinking joining the corps? Just fast forward to the last day of boot. Not marching on the parade deck, but the part when your declared a Marine. Thats the moment you realize it was worth it and you made it. This is no different. You need to see that there is a lot of hard work and pain coming. But if you work hard, keep focused and give all the effort you can, You can work through this and even though you might not ever get it to go away, you can beat the beast and live a good life. Keep up the medication, talk to a therapist as much as you can. Solve the problem in your own way but understand you are strong and able. You just need to want to. And I think you do or you wouldnt have come here.
By the way? Welcome and Its nice to have you in here. Feel free to post questions, put up a rant....whatever you need to do. we are all here supporting each other. And I am glad your here!
