Approaching 40 and feeling lost as the children need me less

[LD86]

I am approaching 40, my children are 20 and 15 and don’t need me really as much anymore! I’ve spent my whole life being a mum and now I don’t know what I like, what I enjoy, or sadly I feel like I’ve lost who I am.
I already go to the gym and have started Pilates at home, I do enjoy walking but can’t seem to find a local walking group near me, I read in the evenings.
i would love to make some new friends, I am sociable and get along with all ages and walks of life! Someone please give me some inspiration thanks

I started a different career at 42, OP.

At only 40 you’ve got a wonderful opportunity to find a new path for yourself. Many of us are a lot older when our kids are those ages!

as per the pp, think broadly then narrow it down rather than the other way around.
