Anyone else?

I don't understand what's going on at all ..my husband and I just had a baby in January and I am just extremly overly emotional about everything..I don't know what to do to fix this..my husband can say something just anything and I take it wrong or thinks he was just being mean..I'm to the point I don't feel loved or cared about at all..and I've told him this and he just doesn't understand he doesn't know what to do or say and I always just make it all worse I end up starting an argument with us and we used to never argue we are great together but I want the old me back 😢 I'm really scared he's going to end up leaving me for this...
