Religion can be a source of meaning, community and steadiness. It can also be a source of fear, shame and control. For many people it has been both, sometimes in the same week, and that combination is often the hardest part to talk about.
I will not decide what you should believe. Therapy here is not an argument for or against faith, and it is not a process of talking you out of anything. The focus is on what you actually experienced and how it continues to affect you now: how you make decisions, what you expect from other people, how much room you feel you have to want things.
You also do not need the phrase religious trauma to be here. Plenty of people begin by saying only that something from their upbringing still has a hold on them and they are not sure why.
