One of the hardest things for me in all of this mess was to be angry,for me. It was easy to be angry for my D's.
I knew I should be happy and grateful that he saw the girls once a week, but I wasn't. Like you, I felt like I was dying.
If you were really feeling better this soon into this, I would either think you were in denial or should write a book. As much as it sux, it takes time. Alot more time than we would like.
Honestly, I've only recently started to feel normal. Maybe I'm slower than some. It doesn't matter how quickly or slowly we get there. What matters is that everyday we get up and move forward. Some days are more slippage than anything, but you do it again and again.
