I wonder if anybody here would be happy to give some advice?
I've got a friend with MH problems who has had them all her adult life and variously been treated for depression, bpd and anxiety but none of them seem to fit properly.
She is a high achieving perfectionist in her work life and has many friends but no romantic relationship as she falls for long-distance and impractical relationships only. Her illness manifests as whenever she feels a little bit overwhelmed by something (e.g. too much to do in a particular week) she spirals into feelings of being totally useles and unloveable and incapable and a waste of space as a person. It's utterly irrational and she knows that but she can't drag herself out of that spiral till she's gone pretty far down including panic attacks, insomnia and even screaming fits 
Anyway, I've known her for nearly 20 years and in that time she's become better at asking for help or at least in telling us when she's having a downward spiral, which is a great improvement....but my question is, does anybody have any suggestions as to what I might be able to say/do that would help at all when she shares that she's feeling this way??
Thanks.
