I can relate. I too had a traumatic childhood and when I have talked to my mom about it in the past, she does everything but validate my feelings and memories. She says I'm rediculous too, a hypocondriac. I've tried to explain PTSD to no avail as she seems less and less interested in my mental well being each time we speak. Thus, I avoid speaking to her. It only proves to upset me, who needs it!?
