@Hippychickbbbb Kindly, I don't think you are going to find the support you need here. You sound quite unwell, possibly suffering from complex PTSD, and most people on Mumsnet won't be able to help you with the impact of that on your life and relationships. It can be supportive here but it can also be quite "tough love" and that can be hard to hear when you're not in the right place to take that.
The Complex PTSD workbook by Arielle Schwartz might be helpful alongside therapy. DBT skills may also be beneficial to help with building the inner resources to cope with distressing feelings without resorting to doing unhelpful things, such as overloading others with your distress and trauma and straining your relationships. Rebuilding after trauma requires a conscious effort to rebuild your identity, think about what your values are and how to live them, engage in activities that feel positive, creative or constructive for you, even small things, and try to visualise the future you would want for yourself.
Counselling may not necessarily be helpful if it's just talking, as that can keep you stuck. It can be useful for some people, but if you don't find you're progressing, you may need to find a therapist that has a more trauma informed, integrative approach and can offer something like EMDR to help you process past experiences if you are having things like flashbacks or intrusive memories that affect your day to day life.
