Seraphina, you have written of your challenges before and have been on my prayer list.  I identified with the problem of finding work later in life after I retired earlier than planned (age 65, I was going to work full time until at least 70, on a dairy farm) to move and help care for an ageing mother.  I believe you are in the northeast?  I have a knit sweater I’d love to have repaired if you were closer!
 
I do not mean to think you haven’t been diligent in trying to support yourself, but without knowing any other particulars a few thoughts come to mind.  My mother passed away last March at age 100.  We had moved her to an assisted living facility for the last 1-1/2 years as I was working part time and not always available when needed but could visit daily and take her on outings.  We would have loved to have found someone who could live in her farmhouse and stay with her.  This kind of arrangement worked out well for her mother back in the 1970’s but it seemed impossible to find someone now-a-days.  Or, there are probable families that could use a nanny / help with homeschooling.  These wouldn’t necessarily “pay well”, but room and board and a modest stipend, space and time to do some crafts and sewing, it might work.  If you are part of a chapel you might ask the priest if he knows of a possible arrangement, or place an announcement in the bulletin.  I understand not having socks darned, and I can sew on a button by myself lol, but I’d love to find someone who can hem slacks or repair a pants pocket.  A Craigslist ad might be worth a try?
