I think some social engagement would really help. I get the sense you're alone quite a bit - travel around a lot for work and stay at home on your own when not.
What activities interest you? You mentioned hiking...maybe there's a local group to do that? If memory serves you took a cooking class with your daughter? Hiking, sports, art classes, cooking classes, volunteer activities...etc. Imo you need to figure out what you really like and get involved in an activity in that area and meet folks who share similar interests.
