I was married almost 2 years ago, and the first year was hard. I am bipolar with PTSD and I found myself trying to explain things, discuss it with my husband, and that doesn't work well. Don't find this harsh, but your husband is not your therapist, or your pdoc. Don't try to explain your issues with him, he obviously doesn't get it, or think anything major is wrong. So, if you are feeling really bad, let him know, but other wise focus on making your marriage a partnership and try to meet some of his needs. Be responsible for your own mental health.
And yes, I would call the pdoc and let them know you are having a lot of anxiety being newly married and see if they can help. Good luck to you.
