I think that sometimes when we are feeling insecure about our judgement it's not a bad idea to bounce ideas off trusted others (like you are doing right here!).
While I fully believe in trusting yourself, ideally, when you have been through a trauma it takes a while to get your sea legs.
I found it extremely helpful when questioning my judgement/perspective on something to ask. I balanced that, of course, with my own judgement, but it was very reassuring initially to make sure that I was seeing things clearly.
