I feel like I cannot say anything to my husband

My husband is a very sensitive man. You’d never guess it because he’s in the military and has been for almost 20 years, been on multiple dangerous deployments, and is really respected. But he gets very upset and sad/depressed or angry but any little thing. He cannot handle any big emotion from me or our kids. When one of us is stressed, sad, angry, worried, he absolutely loses his shit and completely withdraws from us. If I’m sad about something he will legitimately not talk to me until I “feel better”. If I’m worried about something he will tell me to stop worrying because I am stressing him out. So I have to mask my emotions and constantly be happy otherwise his mood will flip and he will be miserable to be around. The kids are the same. Yesterday our son was having a meltdown after school because he was extremely tired. He hasn’t been sleeping well bc he’s had a cold and his nose is stuffy. His behavior yesterday was pretty awful but I knew it was just because he was exhausted. My husband could not handle it. He said “what is wrong with him? I don’t understand. Why won’t he stop crying and screaming.” I said “he’s tired, it’s normal for tired kids to act like that” and he was just so confused and like couldn’t comprehend it. I guess it’s because of him being military he expects everyone and everything to be fine and composed 24/7 and when it’s not, he doesn’t understand it. I’ve been having major anxiety lately and I have been hiding it from him. Today he asked me why I looked so tired and I said because I haven’t been sleeping well because I’ve been having anxiety attacks at night and he legit said “well cut it out, take some NyQuil and stop it. It stresses me out.” As if my anxiety disorder is a burden to him and I should be happy and content constantly. He tells me I have nothing to worry about because we have money and he takes care of everything. Basically I have “no reason” to be anything but happy. I just feel like I cannot talk to him about anything. It’s making me question if this is the life I want. I receive more sympathy and comfort from my friends than I do my own husband.
