Decided on balance not to venture into London - the weather, and the fact that DH has a lot he wants to get on with....but coming back to look at Gransnet makes me feel hugged and warm, so thank you all so much for that, though it's also made me cry (but not in a bad way).
I have battled with depression and anxiety for decades, on and off - though during the childrearing years we were both focused on family life, including raising a child with Goltz syndrome and mental health problems, for which there was precious little help or support out there. My mental health has deteriorated markedly over the last 8-10 years, not helped by the break-up of a long standing friendship with a lady I had a small business with for a few years. She decided 5 years ago that she didn't want to work with me any more, but wanted to spend more time with her family (fair enough) but then 'took up with' someone else who became her sidekick and I had to withdraw from all the activities we did together because it would have been awkward otherwise. Mutual friends were more hers than mine, so I had to withdraw and despite trying to keep contact with some of them for a while, they cut me in the same way that Ex-Friend did. I blamed myself, partly - it's never one person's fault, any relationship is complicated at times - but the way she did it was rather heartless ( she broke the news to me just as we were preparing to go to court with DD2 after DD2 was assaulted). Ex-friend also 'dropped' another friend of hers who was disabled and whom she considered a burden, so it wasn't just me.
None of that should affect how I am now - I've had time to 'get over' it, and arguably my low mood and negativity, partly resulting from the stress of my daughter's severe health problems, had affected the friendship, so I can't blame her for wanting shot of me if that's what she felt. I have tried to rebuild my life - joining u3a, trying various groups there, re-establishing some old friendships, but it has knocked my already shaky confidence still further, there's no doubt. And in the last few years, DH has retired, and is enjoying the freedom - I was hoping to feel the same, but I find I can't find much pleasure in the interests I used to have, whereas he is discovering and enjoying new things all the time. I don't grudge him that at all, I just wish I could share them too.
Durhamjen - I do see a reflexologist every few weeks and am seeing her again on Tuesday. I don't have any faith in it as a 'cure' but I do enjoy the relaxing massage and she does often use aromatherapy oils. I hadn't thought of clary sage -there was a time I used to collect oils so I will have a look and see if I have any and try your suggestion 
I have a psychiatrist but I'm not seeing him till the end of March now - I will try and get to see him again sooner. Not sure he can do much - there is only a limited amount of drugs he can prescribe for me as I can't take SSRIs (interaction with migraine meds). My DH is supportive and does his best, but I don't want to drag him down and stop him enjoying his life. It's not easy having a depressive spouse!
So I've decided on a plan for the rest of the day....I will go to the local garden centre to buy new secateurs (! I know, I know, how exciting is that), call in to see a friend, if she's in, then come home, meditate, have an aromatherapy bath, cook dinner and read a bit. Hopefully my black mood will have lifted a little.
But it's helpful beyond measure having support and hugs from you lovely, patient, understanding Gransnetters. Bless you. xxxxxx
