I am sorry you are feeling so alone da Bee ... sadly it is not uncommon especially for those who are older which is why Buzz is so great.
Families grow up and start lives of their own and work and running their own homes takes up more time.
Do your family know how you are feeling?
It's quite easy to feel that you have to be OK and not say that you are feeling lonely or abandoned ... and whilst you're doing that family can think you don't need help or company ... especially if you have always been independent in the past.
My lovely son will drop everything to come and change a lightbulb for me but rarely pops in 'just because' ... he works very hard and I know his free time is precious ... I understand that and can remember feeling the same when I was younger and everyone wanted or needed a piece of me.
I wonder if it would be a good idea to try AgeUK?
They can offer amazing support from befriending to shopping and cleaning or gardening and help getting out to social events ... not just hospital appointments etc ... they have wonderful volunteers who are all police checked and looking to help people who are feeling isolated in their older years at a very reasonable price ... they can help with things like benefits too.
This is a link to their website and they have local offices all over the UK ... might be worth checking out? They are a highly recommended support system.

Sometimes when we have better control over our lives we can find it easier to engage with friends and family and all kinds of people from a happier place and that can have a ripple effect on how people see us and want to engage with us I think?
Anyway good luck and hope it helps you find some respite from isolatiopn AND maybe some new adventures that you could come and post about on Buzz AND share with your family!!
