My advice would be to take your time to settle into not working, Cheryl. I gave up paid work about 3 years ago and it took me a while to settle into not having the routine of 9 - 5. I tried joining a singing group, went off that idea, a bit of volunteering at our local hospital, went off that idea ... I am now settled into a volunteering role with the Side by Side scheme run by the Alzheimer's Society, which I love and will continue for as long as they want me.
Mr OK1 is being made redundant this coming December and to say his job has been (most of) his life is no exaggeration. Time will tell, but meanwhile he is putting out feelers regarding volunteering with our local Canal Trust (a friend's husband does the same, so he'll be with someone he knows) and maybe taking on an allotment.
I guess it depends on whether you need to earn some ££s ... in which case part-time work may be an option?
I'd say I lacked confidence, especially when I stopped working in a role where I knew what I was doing, but apart from a couple of false starts, I am happy with what I do now. If you do take on volunteering, then I can recommend the Alzheimer's Society - they mentor you, make sure you're happy with what you're doing and treat their volunteers well. I've never been asked to take on more than I'm happy with and definitely feel valued for being me. Being stuck in your ways is no bad thing by the way - one of the Alzheimer's Society's courses mentions respect and equality for all their workers (volunteers and otherwise), whatever their 'ways!' (PS Don't let the idea of 'courses' worry you - they're just the usual safeguarding, equality things and are online). Might be worth a google on their website as there are many opportunities for all sorts of people with all sorts of experiences and none - even me!
Good luck, but do try a few things and don't worry if it takes a while to settle.
