You need to get back with the pdoc/psychologist who was treating you for RA. I only experienced a few days of an abuse which had nothing to do with RA & I know that the flashbacks & the depersonalization that happens when stress hits me is real.
Those horrible people who put you through the RA & dealing with the demons were horrible people. I hope that you do not have to associate with them any longer in your life.
The devil & demons are real.....God provides our way of fighting them, but if you don't have that knowledge, it can be that same helpless feeling that you had when you were going through it initially.
Hold onto your good.....don't let the devil or the demons change the good you are holding onto. They can't force you to stop being good but I know that life can feel pretty miserable in the battle.
Every person has an internal struggle between good & evil & we all have to fight hard to keep evil from winning many times. It's a battle but you can win with this struggle to gain the control over the bad that was done to you.
