To add a data point, I found myself, to put it strongly, literally losing the will to live recently: I'm 20 and female and I'm kind of at the emotional maturity stage. I think my brain stopped saying "live! Stay alive!" and started saying "Make babies! Protect babies!", because I started finding the idea of cryopreserving myself as less attractive and more repulsive, with no change in opinion for preserving my OH, and an increase in how often I thought about doing the right thing for my future kids. To the extent that I now get orders of magnitude more panicked about anything happening to my reproductive system than dying after future children reach adulthood.

I'm not sure for what proportion of women the thought process goes "The future wouldn't want me (because I won't be able to make babies)", with the part in brackets powering the rationalisation-hamster.

Fortunately I learned to spot rationalisation from instinct a while back, but I'm still not sure what I can do, if anything, to correct for the shift.
