Thank you, thank you, thank you to all who've posted such kind and helpful thoughts. It really does help. I was tempted to try and delete my post after I'd written it because I felt so ashamed of it: part of me thinks 'You stupid old self-pitying, selfish woman - give yourself a kick up the arse - just realise how lucky you are before it's too late...' but I decided to risk it, because sometimes writing our feelings down is a relief and can help get things in perspective.
In answer to sunseeker, Soutra and other suggesting counselling....I am currently in the middle of a therapy caller Mentalisation-Based therapy (two days a week) and I'm 8 months into the 18 month programme. I feel worse rather than better. My psychiatrist is encouraging me to stick at it, so I am, hoping something will start to make sense, but it feels like being back at school: drama sessions where the young facilitator gives out percussion instruments to bang on (rather similar to my music teaching sessions for five-year-olds!), patronising, though very well-meaning and kind, therapists getting us to draw pictures and reading things into them which aren't there (!), 'community meetings' where we're encouraged to voice any concerns (mostly about the food and whether we can plant some bulbs in the depressing fag-end ridden pots outside). There's group therapy too, where I sit listening to the terribly sad stories from other patients and feeling utterly guilty that my situation isn't anything like theirs. They have good reason for being ill; I don't feel I do, so the guilt is an added burden. My life was difficult years ago, very much so, but it isn't now, and I ought to be able to deal with my emotions better at the age of 60. Instead I feel aged two, going on fourteen. Pathetic!
As to medication, I was resisting it because there aren't many I can take without interacting with my migraine meds, but I was feeling so low that in the end my psych suggested a different one and that does seem to be helping. Unfortunately it has weight-gain as a side effect and I'm no sylph as it is! Finally it does seem to be taking the edge off the lack of motivation and blackness, but not so much the anxiety and it's no magic bullet, of course. I will continue to try my utmost not to allow my state of mind to affect others, which means keeping a mask firmly attached to my face so no-one sees the rather unpleasant, unpalatable truth lurking beneath. If people knew what I am really like, they wouldn't want to know, believe me! And I really, really want to change. The envy spoken of by Sunseeker is a frequent visitor in my head - not something I am proud of at all. It's something I struggle with constantly, and probably always will.
It is a comfort to know and read here that I am not alone in some of my feelings, though I think I am less successful than others at dealing with them. I do envy those who appear 'sorted' and confident and at ease with themselves. It's a state which continues to elude me, however hard I pretend otherwise through misplaced pride!
Soutra, I recognise that weekend thing! I tend to feel better about my own company during weekdays. I am a member of U3a and go to meditation classes (unfortunately these are only monthly) and also Pilates, and I love gardens and gardening - though this is rather solitary, it does bring solace in being outside with Nature, worms and all).
I also used to enjoy textile art, and still have a very small 'cottage industry' dyeing threads and fibres for sale at quilting and embroidery groups and shows, but I used to do that with a close friend years ago, who then decided she didn't want to do it with me any more
. This was a crushing blow, but I mainly blame myself for the split. It meant I had to withdraw from groups we went to as it was too awkward and painful to see her and I had to give up mutual friendships as a result and try to rebuild my life. She was able to continue hers unhampered as if nothing had happened and found a new 'sidekick'. I haven't seen her since; it felt, and still feels, like a bitter divorce, as we had been friends for over 25 years. Since then I've got to know a few other people, gradually re-established a couple of former friendships - some of those who could see what had happened and didn't think badly of me. It's been difficult, and even now if I hear from someone that my ex-friend is doing well, it feels like a knife in the guts - I don't want to hear it!
Enough of that: I am now going to get stuck into cleaning, cooking and polishing up my battered old mask for Christmas. Hugs and grateful thanks to everyone here. Bless you.
