I know exactly what you are talking about. One of my alters came out on my Mom and said some pretty bad things. Or so I was told. I told my parents what was going on,I had not told them yet. Both of my parents told me I was telling lies and that I had gave them more trouble than my sister, who was an alcholic by age 14 and she would leave days at a time. They do not recognize that I have DID. I haven't heard or talked to them for a week. The only reason Mom called was to wish me a happy birthday and she told me She wished I had never been born. My Dad wrote me a letter and told me I was a liar. He never wished me a Happy Birthday. I've not talked to my sister in almost a month.
My t told me that I needed to not go home as much for a while because I needed to heal and I can't do that around my family. I hate to say this but my family are "unsafe people" and they trigger my alters. I do plan to go home for Thanksgiving because my son is down there. So far I only plan to go home three times a year unless there is an emergency or a death in the family. My family chooses to be this way and sometimes we have to go on and do what is best for ourselves. Even when my Mom talked to my T she told her that all I could do was lie. She said she didn't believe that I suffered from DID. I cried for a little time but I have come to realize that in order for me to heal I have to take my life from them and live it to the best of my ability. I am not going to be a victim by their hand. I am going to be a surviver. If you need to talk just let me know.
