Triggers are tough to deal with in general. It throws us out of our preparedness I think and it's harder to deal with when we experience something that triggers us. I think that knowing something is a trigger can help us to work on coping with it to be able to better deal with it. In therapy, did you ever work on dealing with the triggers of these situations of women showing skin or underwear?
You're definitely not alone. The statistics on women and pornography is great, even those without a history of trauma and abuse. I'm thinking that part of the empty is feeling bad about this - feeling ashamed of how you are handling the triggers. Is that true for you? I know it has been true for me in the past.
I think it's possible to work through the triggers so that when they happen, you can counteract them with your thoughts. It's tough, but it's doable. It takes active thoughts to manage the impulsive thoughts, and then following up with behavioral choices to stop the actions that we've previously chosen. For example, if I am triggered as soon as I realize it and can think at all that it's a trigger, I can choose to challenge my thoughts - this is not now, this was then (about the abuse). This is about someone else, not about me. I choose to acknowledge that I'm triggered and I'm having thoughts of acting with behaviors I do not like but have urges to do. I choose not to (then I need to identify what specifically I will do to prevent these/this behavior(s).
In my experience, changing my location, not being alone, and self-talk as well as journaling on what is really going on inside of me has helped.
I will pray for you, but I do hope you will keep sharing and talking about how you're doing. Looking at how to manage things for you. You can do it.. it's tough, but doable.
