constant arguing

I can't take it anymore. My husband and I continuously argue over the smallest things and we have blown up at each other more so now that we have a baby. We both lovenher dearly but I feel like I'm constantly doing everything for her and he does what he can but he works a lot. He is in the military and has to go in on days off all rhe time and is basically on call for anything. We live overseas and so I'm not close to family or my close friends and I've done my part as far as making new ones and trying to create a good network but I feel like our family time is diminishing. He basically said that's how it goes with the Militart and I just need to go with the flow. It's really hard for me to do this because I'm a planner and I'm not sure why but I've been getting more and more angry inside. I'm seeing a therapist and it's kind of helping but I am so tired of constantly arguing. I'm so exhausted all the time and I'm never in the mood to be intimate but dealing with everything has me super overwhelmed. I start off my days pretty positive but small things can really set me off and then I'm just really irritable the entire day. I don't want to fight in front of our baby anymore. I need advice. I feel like Iike our family needs a vacation.
