First off, Whew! At least you get a brief break from the plunge on the roller coaster.
How are you doing at taking care of yourself through it?
Second thing... .we sometime say there is an order to the disorder. There are indeed patterns, and things that help, things that blow up, and things that give you cause to expect a blow-up imminently.
However the pattern of rage/tears/calm... .or rage/tears/rage+/calm/worse rage; that's NOT part of the real order, or real cause of things. It is interesting. It is different. It may have some significance, but none of us are likely to even know if it really did or not.
Instead focus on taking good care of yourself, and using the tools... .which you sound like you are doing very well!
