Let's say a young person in late medieval/very early Renaissance Europe is experiencing a personal crisis and can't/won't approach their family about it. Who else might form their support network? Especially medieval women (of any social class) which relies on a similar premise.

There is always more to be said, and the linked answer uses mostly examples from what is today Germany. I hope someone will write about Florence specifically.
