I am so very sorry for all that you have been through. The law is often not fair in these matters. Generally states have not granted any unique right to sue even the most abusive of parents. Any cause kf action would have to be based on some theory of law like fraud or breach of a contract or physical assault. There have been attempts to sue a parent for emotional abuse and basically courts have dismissed those claims.
It seems really unfair I know. The law is sometimes very unfair.
