@Gwynn Also wanna say that I think it's OK the grief still lingers. Grief is a normal response to trauma. If you need to grieve for what has happened, do it, you deserve to acknowledge what happened and mourn
The other thing I usually suggest for people who struggle with trauma of a night is to make your bedroom as engaging as you can stand. Create tactile sensations everywhere. For me, I find it helpful to have things my physical senses can respond to straight away when I wake from a nightmare. It helps to pull me out of it quicker--I think so anyway. I use a white noise app, have a scented room spray sitting next to my bed, and also invested in some nice bedding. I don't sleep with socks on, I do this thing where it's like walking while in bed so I can feel the sheet rubbing on my feet. It sounds very weird but it's just that sensory thing, it's grounding. Anyway that's enough embarrassing tips from me.
