Hi restless, I am so very sorry for all the pain and uncertianty your going through in your life right now. I was wondering if perhaps your psychologist could refer you to a counselor? This would be someone that you could speak to and try to work some of these feelings out one on one and help give you some problem solving techniques to use with your panic attacks and hopefully help with your marriage issues. You could see them inaddition to your psychologist/psychiatrist.
I feel I am the last one to give any kind of relationship advice at all as my own marriage feel apart 3 years ago after being with him for 12 yrs and 5 yrs married. It was the hardest thing to go through in the world and I did feel like I would never try again or be with anyone else ever again and basically my whole life was over. But you have to know that you are an independant person regardless of your relationship and you have to take care of yourself first and foremost before you can make a relationship work. For those of us who have abusive pasts we tend to make ourselves so small, our worlds small as in isolation so that we cant get hurt again. What ends up happening is that we have made this protective shield around ourselves so solid that we sufficate ourselves and sometimes others. Thus the depression, panic attacks and post traumatic stress. I am not saying this is what is going on with you...but I have done this with myself and it is a hard pattern to break.
Please do look into the counseling idea, I think you will find it helpful for you in the long run. Maybe if the weather is nice where you are take a walk and try to clear your head alittle. Sunshine is a good boost for the emotial system. And always know we are here for you.
Hugs
