Triplet Shock

Found out yesterday at my wife's six week ultrasound that she's pregnant with triplets. Each appear to have their own yolk sack, and are roughly the same size. We're in our early 30s, and this is my wife's second pregnancy after a miscarriage last year. We're both in absolute shock, and cycle between being incredibly excited and totally petrified. It feels like a hallucinatory experience, and I've hardly been able to sleep since yesterday.

I know its very early and a lot can happen in the next few weeks, but doctor says there's no reason right now to think all three won't be viable. I'm struggling to fully grasp just how radically our life is going to change. We currently live a few hours away from family/close friends, who are mainly concentrated in one city. I recently switched to a lower paying but much better WLB job, which now seems like a huge mistake given how expensive this is going to be and that my wife is probably going to need to exit the workforce for a while. I feel like we need to start making plans now to move to the city where all four grandparents live; I need to start urgently job hunting again; we need to sell our current cars and purchase new vehicles, etc. Not to mention the fears I have about this being a high risk pregnancy and all that entails.

Any advice or words of encouragement would be appreciated from folks who have been in a similar spot.
