Scapegoat

I grew up in a family that has been both physically & emotionally abusive. I guess I have been the scapegoat of the family. I do not like this position and want cut all ties with my still emotionally abusive family. Is this a foolish idea?

I have fibromyalgia, chronic fatigue and high blood pressure. I feel like major crapola after I suffer a bout of abuse from my family. This can happen at least once or twice a month. When this happens the depression, anxiety & pain kicks in big time; then I withdraw from others.
