Husband with depression FTM

I'm a first time mum and am struggling to support my husband who suffers from depression. My daughter is nearly 4 weeks old. SO says that now I have a baby I don't care about him like I used to and I don't listen to him anymore. I'm breastfeeding every 2-3 hours round the clock, trying to keep on top of the housework and I'm also trying to kickstart a freelance career so that I don't have to go back to my office job after maternity leave. So yes, I've changed my approach a bit. I've decided plans to tackle the things my husband worries about and we can do stuff about (ie work, money etc) and for the things we CAN'T do anything about (ie no time for writing/hobbies anymore, existential dread, family issues etc) just to stop worrying about them until the point where there's something we can do about them and THEN fix the issue. I was away at my parents house the other night and called him because baby had been cluster feeding between 11pm and 1am and I was starting to loose my cool so called him and before I'd even told him my issue he launched into a conversation about his worries and how rubbish he was feeling - most of which was irresolvable or we already have plans in place to tackle. Of course i was short with him!!! And I've continued to be so because I can't keep going over and over old ground. I'm exhausted and need him to at least be self sufficient... but ideally supportive of ME. I can't be mum to both him and my baby. what can I do to a) be less angry with him b) actually make some sort of difference?
