Is it appropriate for me to express to my teenaged (birth) daughter that some of her words and actions have really hurt me?

I am sure that she did not intend to be hurtful, just thoughtless and insensitive-as teens can be sometimes I guess. Being an adult, it feels strange to express to a teen that they have “hurt my feelings” is this even appropriate? I feel that I must do something though, because I am concerned that my unexpressed hurt is slowly starting to brew into resentment… I am also concerned that if I express how I really feel that I may lose the relationship with her. I do not have anyone to talk to about this, and frankly, this is the one subject in my life that makes me feel like a vulnerable “kid” myself sometimes. Any point of view would appreciated.
