DD(14) has CFS/ME and has been ill for nearly 4 months. She has been off school for all this time. It will take her 2 years to recover which will affect her taking her GCSES. It's a pretty monumental thing to happen to us as a family.
I know they say that you find out who your friends are in times of need and that some people step up and shine and others fade into the sunset. But I'm surprised and hurt by some friends' reactions (pleasantly surprised in some cases though).
I emailed her godparents a couple of months ago and a week later received a reply saying 'sorry it look me so long to reply, I didn't know what to say. Poor you!'. Then nothing at all since, not even to ask how she is. 
I've not really put much on FB but did update my status when she was diagnosed and then more recently with a post to raise awareness for ME as it's ME Awareness week. It was a 'walk in my shoes' post and an account of what it's like to live with ME day-to-day. I haven't harped on about it but there is no doubt that it's serious.
I've been really disappointed at supposed friends who haven't commented on this or even just 'reacted' to the post(s). I have had RL contact with some friends so they don't count. But other 'friends' have literally done nothing, even though they have been on FB, liked other people's posts and updated their own statuses.
So AIBU to think that a friend doesn't feel moved by what we're going through and/or want to offer a word of support, they're not really someone I should class as a 'friend'? In RL too not just on FB. Just generally.
