My stepmother represented herself to me as a mother for 25 years until my father passed away. Two weeks after he passed, she invited me to lunch and told me that we never had a relationship and she did not want to have anthing to do with me. Not only did I lose my father, but an entire family that had been together for 25 years. This has caused me severe confusion, hurt and depression. I can't sleep or concentrate on much else and my work has been affected. Even leaving my house has become a chore. I have started therapy to try and work through this, but it just keeps getting worse. Is there anything I can do to hold her accountable for this?
