Am I wrong to feel this way

Hi there, i guess i just needed to vent about my relationship at the moment. We've been together for 4 years and its been almost perfect with the exception of he struggles to find work or keep a job for more than a year. We had a baby back in September and our baby had to go in to a childrens hospital, luckily our baby is fine now but im noticing or feeling like his priorities aren't right. He gets annoyed or angry if he cant game everyday, he still doesnt have a job and hes not a nice person in the mornings towards me(shouting at me for little things like going to the toilet whilst waiting for the kettle to boil and the baby is crying). I feel like im justified in being frustrated but every time i try and talk to him about how I'm feeling, i feel like he turns it around to being my fault, like i put too much pressure on him or i nag him too much. I am fully aware im not perfect in all of this, I've got postnatal depression and i already struggle with distress intolerance disorder and other mental health issues such as self harm (which I've not done for nearly 2years) as a result of a traumatic and abusive childhood so I'm sure I'm not the easiest to deal with sometimes. I truly love this man and we just click and have done since the day we met but recently i just dont know what to do. Im confused, i never know if I'm being unreasonable with him or if he genuinely needs to step up. I've always looked at it that now we're parents that we need to except that we can't do what we want whenever we want anymore but feels like he doesn't want to except that. I dont know anymore, i just want us back and for our baby to have a happy life.
