welcome...

You must be very worried and scared right now.. and I am so sorry... this is such a diffcult illness to cope with...and you are such a caring mom... to be so very concerned...

I guess.. I can only give my opinion... from the point of view of having an ED... and I am also a parent.. of a young adult

from your post... I can't tell if your daughter is an adult , young adult or a minor.. and I guess I would treat the situation differently...

so assuming.. she is young adult...

I would talk to her... and try to see.. what is going on in her life.. right now.. that might be causing a relapse..

and then.. I would want to try and figure out if she has "relapsed already".. and the "might" is letting you know... that she really has...

For me... this would be important.. to find out..because.. it means more immediate action...

And... then I would talk to her about... not relapsing..how important - without "nagging"... for her health it is.. and how very much you love her.. and how important she is to you....

and then I would talk about.. "fixing" making better whatever pressure that is causing this feeling....

hope this helps... and doesn't hurt...

sincerely, freewill
