Is there a Extension group or garden club in your area? I married an only child and moved far from home. Everyone seemed to have social groups and women my age were school buddies or had extended family ties. I was introduced to the WVa Extension Homemakers' Club and later Garden Club. These ladies were retired but active women and became like grandmothers to my boys. I felt right at home with them and now I'm their age and I still miss them like family. I hope you find friends soon.
One thought is to find out if there is a group sewing/quilting for charity. Seems they would welcome help. Church was/is a place to make connections. Good luck.
