Need to calm my RAGE before I go to work.?

I need advice quickly... My wife has not physically intimate with me for almost a year now. She ignores or rejects any attempt from me 99.9% of the time. Married for five years, mid 30's. On the way out to work I put a doent on a usb key for her. She saw a couple of ographic photos on my PC as I was transferring the file. She said, "Don't put that on the Flash drive for me" kissed me goodbye and left for work. I am nothing but loving to her. I'm on my way out to work but I feel so ANGRY and ENRAGED right now I could scream. I guess the bitterness and resentment is just boiling up right now. I don't want to feel like this going to work. How the Hell do I calm myself? Help! I'll check replies on my phone.
