@Covertsadjw - There is a grieving process to go through just like with a death. Look up the steps of grief and you'll go through them all. You may need to vent your anger. Reading here helped me, as did posting occasionally with a rant if necessary to let it out. Unfortunately you're still living in the middle of crazytown, so that's going to make it harder.
The anger comes in waves. I still get that way at times. It's all a process of processing. Decades of cult involvement don't just go away. I heard it said that it's like deleting a file on your computer. It doesn't show up but it's still there and recoverable. Over time things get written over it, bit by bit, but it takes a long time to go away and is still recoverable by programs or experts.
Maybe going to a therapist for help in processing and dealing will help. Or go to one of those places where you get to break stuff in a room for a price, lol. Music helped me at times. A good angry throwdown song released some pressure.
