I find it much more difficult to feel emotionally safe than physically safe.
I'm working on surface stuff right now to help myself feel more emotionally safe, like adding structure to my da0 such as having a small agenda of minimums that I try to do - i.e. putting entries into my health journal, writing in my regular journal, reading my devotional and prayer, toning/stretching/strengthening exercises, working on eating better and taking vitamins, adding a creative activity, music (always), etc... Practicing self-care that shows me that I care and am trying to provide a safe environment in my own company. I can't always control what memories pop into my mind, but I can be alert to their intrusion and speak to them. I also record these activities and acknowledge them, telling myself that I am worthy and showing myself that I can take care of myself. It's back to basics for me in this regard.
I think self-care pairs well with self-compassion when the memories or feelings surge. I tend to act out, so the compassion really helps pull me back from the edge a lot. Also being able to practice mindfulness instead of judgment when my first urge is to run to behaviors because of a core belief that I am not strong enough to manage emotions can be powerful. I always record these wins and honor them for what they are showing and telling me about myself that I need to know. It's like I have to find enough light to fend off the darkness of the lies I've been told about ourselves or the world. Sometimes a visualization, like a mantra, can be helpful. I use those quite frequently.
Don't know if any of this applies or can be of help to you, but am hoping as I know this is rough terrain. Sending a candle to light your way. Best to you. VB
