Not alone in what you are feeling. Irritability/rage can consume without good reason. I feel as if sometimes I could rip the head of some, spew down their neck and sit their head back on leaving them the needle and thread to sew it back on while I walk away. It's hard as I easily could take that rage out on my children. I was going through my divorce at the time of my first deployment so I cannot relate to having my spouse leave me due to my PTSD. I struggle daily to keep a smile on my face at work but usually by the time I get home, I want to rip into someone, and the easy targets standing there are my kids. I have learned to tell them, hey mom is in a bad mood, and thankfully they understand. I used to drink like a fish out of water, but one thing therapy (while I was still active) taught me was to cut back on that. However, struggling with no sleep, being tired from no sleep, only fuels the rage that swells up from within.
