does anyone feel utterly sad...is this depression or post viral blues

[Gatekeeper]

After a month long virus and a difficult year I woke up a few days feeling unbearably sad and yesterday cried my eyes out in the loo. I've been crying off and on today as well and feel awful- almost bereft

Dreading my darling girl leaving for uni next year, dreading ds doing the same in 2 years. I'm 56 and feel like life is slipping away with old age and illness/death looming. Sounds daft and pathetic but I can't shake this off...dread, melancholy. Normally I am content with life but I'm suddenly afraid

Me too!
I've been having a lot of headaches and then I got heavy cold/flu like just before Christmas and I just feel like sitting in the corner and crying. Only thing is that will make my head worse, so I'm trying not to.
Not sure if it's aftermath of illness, stress (something has been causing me a bit of bother) or something else, but I don't normally feel like this, nor am I often ill.
Might try that St John's Wort.
