Self-respect is a biggie too.
I learned it as:
Self-esteem = Self-Acceptance + Self-respect + Self-responsibility
• Self-Esteem: the view and opinion you hold about yourself and your worth
• Self-Acceptance: I accept who I am, I accept trauma, I accept my PTSD, I accept that it's not fair, I accept that it sucks, and I accept that I cannot change it. It's basically the serenity prayer applied to our personalities, our disorders, our bodies, etc. It doesn't mean you like it or agree, but that you've stopped denying it or fighting it.
• Self-Respect: integrity, building confidence by keeping your word and meeting your goals (internal); setting boundaries and enforcing them with respectful assertiveness (external)
• Self-Responsibility: the belief that you can effectively see to your needs; for me as a PTSD sufferer this has been the work of believing that "I am no longer the child I was. I am not helpless now. I am not powerless now. I have more knowledge, resources, emotional tools, freedom, options, and physical strength now. There really was nothing I could do then. But this is now. This is different. I now have the autonomy, tools, resources, and strength to see to my own needs AND/OR to seek out help to do so."
