Please help I have a pregnant wife with a dying mother!

I got on here to ask questions and start a discussion about my current situation. I have a wife who is great. BUT three weeks ago on the same day, she found out that our IVF process worked and she was pregnant and also that her mom had a terminal brain tumor deep in her brain. She has about 3 weeks to live best case scenario

Needless to say its been an intense month.

Problem is that empathy and thoughtfulness is not my strong suit and I am not doing a good job of supporting her. The whole IVF process is intense and we aren't really allowed to have sex. The cancer thing is making her depressed and angry and we are not in a good spot as a couple right now.

Plus I make it worse because I just want to get away so I drink and game with my single buddies. Its hard to be around such a sad energy all day everyday. She goes to bed and wakes up crying

My brother is a super nice person and he would be fine in this situation but I am crumbling and the worst part about it is that my wife is losing her mom(best friend)

Does anyone have any ideas. I know you might say 'hey maybe don't get hammered and game with your idiot friends' like my wife says and maybe it is that easy but if I don't I'm going to lose my mind.

I wish I wasn't as selfish as I probably am but I want to be there for her because she needs someone who is. Im doing a bad job and I love her very much

Any thoughts or ideas. Please
