please give me advice.

So, my boyfriend has been super depressed.. I've dealt with this before with him, but this time seems to be different. We got into a really rough time lately, and last night he just told me how he felt. I knew before hand he was upset, I could see it in him. But this time, I'm just lost. I'm typically the kind of person that when I'm angry, i yell and such. I have to throw an argument around before I can chill out. I also get angry when he doesn't open up to me. I know that I need to work on those. And especially be there for him right now. Are there other things I can do to help him? Like me personally? Please help 💜
