Terp you've come to your own conclusions about this, which is that working on yourself is all you can do right now. If you're heavily depressed and suffering from PTSD you're not going to be thinking clearly. The fact that he's caused this but still doesn't get it would infuriate anyone, and unfortunately that's also something you have to carry. Not fair.
At least there's a lot of reputable information out there about how you can help yourself with depression and anxiety, while working with your therapists. Make it your project to get yourself as well as you can, but you can also reach out for help. You're not on your own.
