Hello brendaj. I totally understand your feelings. I have 3 daughters, 1 in north London, 1 in SE London and the other in Cumbria and we are in Somerset. I was diagnosed with cancer 5 years ago and nearly died after the first chemo session, but none of them came to see me. Infact, after my hospital treatment was completed, 2 of them complained that I wasn't helping them enough! My DH thinks it is the facebook generation that have become very self-centered. This doesn't help you at all other than perhaps to understand why they are like this. And yes, I totally agree that moving to be nearer them probably isn't the answer. I started volunteering - it's different from working as, if not well, I don't feel guilty about cancelling. But it helps with your feelings of self-worth and may help you make friends too. My friends really help me when I need to moan, or need help with hospital appointments etc.
It is really tough and I do so empathise. Oh, just one idea to help, possibly - I do a lot of craft stuff, knitting, crochet and sewing for the family and friends and now for our food bank - it keeps me occupied and gives me a good feeling when I finish something! Lots of love!
