How concerned should i be?

[boyfriend1121]

For the last couple of months my girlfriend has been dealing with some serious eating problems and self-image problems.  I'm at a point where I'm not sure how to help her.   I wanted to know if I'm overreacting or if my concern is warranted.  
For a while now she has become obsessed with her weight.  This plays out in several ways: she becomes very emotional and isolates herself b/c she doesn't want anyone to see her "b/c she is so big" (3-5 times a week), taking multiple showers everyday, counting calories very closely, talking about how stupid she is for binge eating (a binge to her is a pretty normal meal).  She also tries to eat very healthy, she sticks to fruits, vegetables, and organic food, and occasionally fish.  But her diet is greatly lacking in variety.  I think most days she doesn't even break 1200 calories, but i suspect she frequently falls far short of that amount.
A month ago she built up the courage to go to the nutritionist, but she only went twice.  She freaked out when the doctor suggested she see someone who specialized in eating disorders.  She is scared to death of doctors, and even more afraid of being diagnosed with a mental disease (some depression and other mental disease in her family and she refuses to become apart of that).
Long story short, i've tried to help her but her response is always that she is taking care of it (its been months now).  However, when she say shes taking care of it she just talks about eating healthier, not binge eating, and "not being fat".  How can i help her? How can i get her to get help?

A little information:
She is 5'8''
She is 119lb
She is very honest with me
She has tried to throw up on several occasions (unsuccessfully)
She frequently takes laxatives when she starts to feel like she ate to much

Sorry for the scattered post, i'm just trying to not leave anything out (but i'm sure i have).  Thanks for the help.

since it looks to me like you care about her &love her very much. let her know that you're worried about her &you only want the best for her. encourage her to seek help. seeing a doctor or a professional &seeking help is only going to make her stronger because she had the strength to find help &get better. it sounds like you've done what you can to try &help, but it's time she see that this isn't only affecting her, but the people she cares about as well. that's what it took for me to break through.
hope i helped.

wow first of all 5'8 and 119lbs??,,,,thats REALLY skinny.... im also 5'8 and im 160...im NOT fat by any means.... i have a few extra lbs but not chubby or anything.... at this height we are supposed to be around 145-155lbs......she isnt even 120....im glad to hear that your trying to help your girlfriend, but she needs to go see a doctor to make sure she isnt cause herself any damage. it sounds like a eating disorder or one is just around the corner.. i know you cant watch her eat and make sure she is doing it so all you can go by is what she tells you.1200 calories a day is what an INFANT needs a day to be healthy.

sit down and have a SERIOUS talk with her.... get her on this website if she doesnt want to go to the doctor...try and get her to talk to a doctor on here..... there is alot of support for her here.....good luck....keep me posted...
