welcome.....
and... you are a very caring person for wanting to reach out... and wanting to say something....
it is hard.... to know what to say to a person who has an ED... I guess.. having an ED... and having had a friend with an ED... I have experienced both sides of the whole issue...
May I ask... when she contacted you.... what was the "tone"... of her contact.... "depesrate"... or "hi how are you"... or " here I am.. and I have an ED"... it might help you to figure out what to say...
In general.... just saying "Hi"... perhaps... and "I have thought of you.. and wondered how you were doing"... might... be... a way to go...
or... I know I will most likely "take heat for this".... perhaps it may just be so uncomfortable for you.. that to do nothing is best for you.. - and I think that is ok too... practicing self-care....
welcome again to PC... and to the ED forum...
