I do not understand why your family would invite you if they did not want your company. That makes no sense. Did they think it would be fun for them to ignore you? I am so sorry that your family is treating you this way. To me family is just that "Family"! Family is for support and Love and encouragement and all those things that help a person know they are loved. I can not think of a single reason to do this to you. For your own sanity, I would nicely decline any offers to spend time with them. Tell them you are busy. They do not deserve your company.
