In reply to RX-78:
It would be an individual thing, I'm sure, but I gather that it's once a partner dies that it can become more of a factor, women seem to survive better/live for longer following the loss of a partner than men do, because of having more connections with people to use for support, with emotional and physical health being intertwined.
I have a loaner streak in me, too, but for the people I care for, I kind of can't do enough for them, so I try and direct a bit of that towards making new friends, because I know it'll do me good in hard times, and a proportion of the friends I make turn out to be worth making (most importantly). I was very glad I did once my Mum passed away, I wasn't up for having Lucy and Joe round for tea with Lucy offering to bring the food, but it meant it a lot to get the frequent offers.
It can take effort, but it's good. The sexes can have different styles of developing closeness, but women perhaps generally have it sussed in knowing the importance of connections.
The self can be changed more than I appreciated....
