hello @Billie-Jean
Firstly, can I just say that I think that you are extremely brave in opening up about your mother's illness and resulting upbringing, traumas that you endured.
The fact that you were separated from your mother for such long periods over the years during that tender age would have been extremely traumatic. Added to that horrendous circumstances of domestic violence and abuse.
I have myself experienced domestic violence and abuse. This led eventually to my suffering ptsd for several years, now given another name, complex trauma. Not sure where the line starts, stops. another label.
For me when experiencing dissociation or dis-integration strongly I find grounding myself the most helpful.
Planting my feet firmly on the ground and feeling the weight of my body flowing through to my feet, anchoring myself to the floor. Fixating on something whilst doing this preventing me from falling over. I try to look through a window if I am inside, so that I can see the real world, sky, clouds, trees, plants. Observe any interaction with the sun, wind, rain etc.
You can also tune into sounds around you, birds, animals, traffic, people.
You are basically distracting yourself without focussing on the term distraction.
There are many people on here who have been diagnosed with BPD. If you feel comfortable, continue to write your thoughts or questions on here or respond to threads of others. There is no hurry, no right or wrong way either. in your own time, as much as you feel comfortable sharing.
You are safe and will not be judged.
I wish you a safe journey and am pleased that you found us here.
