miranda- What you last posted was very helpful! I actually was reminded of an anorexic I once knew who has since died of from her lack of eating- her controlling of food seems to meet many of the criteria you listed.
I worked with only one cutter in my time with my work with the mentally ill. (As a promenant feature). She was very independent and well into her 40's. She cut her arms both on the inside and out. A lot. So much that I couldn't tell what was new and what was old from day to day. I checked her arms daily before and after she left home, and sometimes her arms were so raw, there was no way for me to know if she had "recently" cut (like within the last day or hour etc). She experienced (she said) flashbacks constantly of her being abused by her father. This was before Geodone and Abilify that have helped people with flashes.
I now see a woman now who has less flashbacks than ever (used to be daily) and she has a history of "trying" to cut (an urge) but hasn't. She is in her 40's and her father had sex with her from age 7 on into her teens. Her head is dented from when he smashed her head with a baseball bat. She is blind in one eye from this. She has never cut herself and I think she is one of the most heroic women I have ever met! She has problems but is dealing with them through therapy very consistently! (DBT therapy- esp. designed for ptsd)
