Starting process now, dissolution meeting later this month.

My wife makes nearly 100k a year, and I 40k. I’m initiating the process. We have two kids, 8 and 6 and are on my medical insurance. I work M-F 7-3:30 and she works nights at a local hospital, 7p-7a. I don’t want to feel absolutely crushed by the process, but I do not want to feel anxious about financial stability. Any advice?
