Hi Sheila, I feel for your situation. Loneliness is tough enough, compounded even more by geographical isolation, limited transportation, tight budgets, and, yes, getting older.
My future is probably going in that direction, too. My boyfriend is twenty+ years older than me. All my friends are his friends (many of whom, in the same age group as he, are having trickier and trickier health issues due to aging; a couple have departed). I have no children. And, because I am no longer a Christian myself, though my family is very strictly so, my brother said he didn't think I was a good influence on his son, my dear beautiful nephew. My nephew is now twenty. I've tried to contact him -- to no avail. My niece is 13, I think, a real creative beauty who I would love to meet again, but...
Thankfully, I live and teach in a college town. I'm around college kids all day -- I adore them. My colleagues and I are not close for anything other than office chit chat. I don't like to drive to places by myself, and certainly not at night; and, although I'm very comfortable in the classroom, social gatherings outside of the classroom are laden with jaw-clenching discomfort.
I commend you, like others here have, for your determination to find a better church. How can a congregation not have compassion for someone in a crying jag (which is highly indicative of trauma, posttrauma). Shame on them -- may each one of them learn in the future how to recognize traumatic experience.
I hope this place will help you. I know I don't feel as isolated since I started posting.
Best hopes for meeting new friends.
