If a family member is the caregiver and takes more verbal and physical abuse from the patient, what can you do?

Paradise I wasn't lucky I got help from a rape crisis counsellor... not counselling per se but an explanation that abuse is nothing more than the insecurities of a bully intent on gaining power for themselves and that the best revenge is to be the best person you can be and to stand up and be counted for the things that are right and to expose the things that are wrong in this world. This words meant so much to me and I try to live by them. I have lost jobs for standing up for the right things but I never lost my dignity. I have lost 'friends' for criticising things I believe are wrong but I stand by my comments. I am a gobby cow and I get a lot of things wrong but I do try especially when it comes to the serious.
