Should I try and talk to my daughter who is I feel very down.

Daughter aged 25 split deomm boyfriend before xmas last year. She also started new job Feb as Deputy Matron on Mental Health ward.She is very insecure, dyed her hair black and severe makeup. Friends have noticed she looks funny but she is very snappy. She is obsessed with her looks but actually looks funny. She is a very pretty girl but at the moment looks hard. How do I handle it.

I wouldn't lecture, criticize her behavior or try to tell her how to dress. Ask her soft questions, listen to what she says and try to understand. She will only change her appearance when she believes it's necessary. You will have more influence over her with a close bond. Hugs work better than lectures.

It is important for older members of the family to understand that what younger people consider cool today is much different than their generation. From tatoos to hair dye, this is the "do your own thing" generation. I don't read anything in what you say to indicate she has serious mental health issues, it just sounds like she has a much different idea of fashion than her critics.
