I think it's really important to reach out for as much support as we possible can, 1313. You sound like you're on the right track.
I'm struggling right now on that front after a remarkably bad week, but I did reach out to my IC immediately after the latest crisis (for my second appt this week!), and have spent a lot of time with my parents. I'm trying to find a DivorceCare group, but not having much luck - the local ones are all in their later meetings, and I really need the early ones about dealing with the initial crisis, anger, depression, etc.. I did just sign up to join a Meetup Beyond Affairs Network, not that that's exactly where I am, but it's part of the problem and any support is a good thing right now. They have to approve my membership. so waiting on that.
I'm glad to hear that things are calm in your situation right now.
